When I did my Computer Science degree the vast majority of courses were 50% final, 30% midterm - even programming exams were hand written, proctored by TAs in class or in the gymnasium - assignments/labs/projects were a small part of your grade but if you didn’t do them the likelihood you’d pass the term exams was pretty darn low.

We already had AI proof education.

I personally dislike placing a heavy emphasis on exams. Assignments/projects have been consistently the most enjoyable and rewarding parts of the courses I've taken so far in university.

It's a shame that they are also way more susceptible to cheating with AI.

I went to college as a MechE so unsure if compsci was different. But overall, all the “fun” projects were labs. We have three semesters of hell and all 3 semesters had 2-3 labs, and we write 20 pages or so for EACH lab a week (usually a team of 2-3).

by gpm 3 hours ago

Also way more susceptible to cheating in traditional non-AI ways. And your mark ends up depending a lot on how much time you have to invest independent of how good you are at the course material.

Assignments and projects are great for learning, but suck for evaluation.

I really appreciated classes where there was rapidly demising returns to time spent :)

Another example, lit classes where the grade is based on time limited, open book exams, hand written in "blue books"

Read the book, pay attention in class, spend 90 min writing an essay, and you are done.

is evaluation that important? ultimately if you can't do the work you're only cheating yourself in the long run...

by antonymoose 27 minutes ago

You say that but I was a Class of 2013, aka during the massive hiring boom of the teens. I tutored a friend of mine with a Ds get Degrees mentality who eventually graduated and now works an ass-in-seat job for Booz Allen or one of those types. I used to joke about it with another friend, that his diploma ought to include an asterisk and a half dozen other names for how much we ultimately did on his grades take homes. I’m pretty sure he makes about the same as me by now purely on tenure.

Personally, I dropped out despite a full ride+ becuase why would I put in work for a no name state school when I already has an FTE job as a developer out of high school anyway.

Turns out fraudulent action can still get the bag.

Part of the purpose for evaluation is to provide feedback. I'm not going to claim that the form of feedback is great, but it does offer motivation to improve.

The other thing that feedback feeds into is credentials. I realize that some people are dismissive of this aspect of the degree, but it is important to pursue further studies or secure a job. While you can argue that these people are only cheating themselves, and some of them are cheating themselves, a great many will continue to cheat as they advance in academia or the workforce. In other words, they are cheating others out of opportunities.

by musicale 2 hours ago

That is the traditional view, the view of those who want to improve their own knowledge and abilities, and presumably the view of those who would like to consider the degree to be a meaningful credential.

However I suspect that there are many who 1) are more concerned about the short term outcome, 2) consider the degree/diploma to be little more than a meal ticket or arbitrary gatekeeping without any connection to learning, 3) view the work as a pointless barrier to being handed said diploma, and/or 4) don't see the value of human learning in a world where jobs are done by AI and AI systems routinely outperform humans on complex tasks.

Then I suppose we can go back to having computer labs that can only access white listed domains and other study materials. Students code there to ensure no cheating.

Syntax seems like a stupid thing to test in university level courses. That's trade school stuff. And I don't mean that as a criticism of trade schools, they just have a different focus.

Half related: reminds me of my physics teacher's test of how observant we were. The extra credit question on the test was "what is your teacher's favorite color?", which she had so far given no indication of. But while watching us she was walking all over the room in every possible direction, because the answer was on a piece of paper taped to her back.

In one of my classes the approach was the opposite, I’m expected to do Ph.D level work as an undergrad and am expected to use AI.

In a different one she just said so long as you say AI was used you’re fine to use it.

In the rest of them AI is considered cheating.

To say we have discrepancies in the rules in an understatement. No one seems to have the exact answer on how to do it. I personally feel like expecting Ph.D level work is the best method as of now, I’ve learned more by using AI to do things about my head than hard core studying for a semester.

by terrabitz 37 minutes ago

It's not inherently contradictory, just like using a calculator could be considered cheating depending on the context. If you're just learning basic arithmetic, a calculator is cheating since it shortcuts the path to learning. OTOH in calculus, a calculator is necessary. You still have to have a deep understanding of the concepts and functions to succeed.

It's still a new tech so I'm not surprised a lot of teachers have different takes on it. But when it comes to education, I feel like different policies are reasonable. In some cases it's more likely to shortcut learning, and in other cases it's more likely to encourage learning. It's not entirely one or the other.

by Izkata 15 minutes ago

A better example might be physics and math classes. I was learned derivatives and integrals at the same time in those two classes, but the math one required we learn how it all works (using limits to understand why the derivative rules work, without using calculators, for example), while in physics we just memorized the rules and were expected to use the calculator.

How do you know you actually learned, instead of being fed slop by the AI that isn't true at all? If you didn't study, then I doubt you'll really know if the AI is lying to you or not. I have to wonder if your teacher will too, sounds like they have kind of checked-out from actually teaching.

Soon on Show HN: I built an open source tool that controls your electric typewriter.

by whartung 5 hours ago

What's interesting is that as I understand, folks are using things like Google Docs for papers, and that it's (apparently) straight forward to do analysis on a Google Doc to see, well, the life of the document. How it was typed in, how fast, what was pasted and cut back out.

My understanding is that the Google Doc is not a word processing document, it's an event recording of a word processor. So, in theory, you could just "play back" watching the document being typed in and built to "see" how it was done.

I only mention this because given the AIs, I'm sure even with a typewriter, it's more efficient to have the AI do the work, and then just "type it in" to the typewriter, which kind of invalidates the entire purpose of it in the first place.

The typing in part is inevitable. May as well have a "perfect first draft" to type it in from in the first place.

And we won't mention the old retro interfaces that let you plug in a IBM Selectric as a printer for your computer. (My favorite was a bunch of solenoids mounted above the keys -- functional, but, boy, what a hack.)

That's certainly one way to abstractly automate a task: Just pay someone else to do it. (This is a concept that regular people employ every day in the real world.)

Another way to automate this particular task is that some typewriters have (serial/parallel) ports to connect to a computer. It's not a daunting task at all for a student who is skilled in the art of using the bot to have one of these typewrites be the output target.

Like this: https://chatgpt.com/share/69e405db-1b44-83ea-baf3-6af41fe577...

Even Microsoft Word stores revision history inside .docx files, and that’s been used to expose plagiarism. I heard about one case where a student took an existing paper (I believe from a previous year/student) and pasted it into Word. They then edited it just enough to make it look different.

However, they didn’t remove the embedded revision history in the .docx file they submitted, so that went about as well as you can expect.

You should look up the history of the Loebner Prize [1]. There’s a shocking amount of technological development in some chatbots that went toward simulating mistakes and typing patterns to make them seem more human-like.

In some of the later Loebner competitions, when text was transmitted to the human character by character, the bot would even simulate typos followed by backspacing on screen to make it look more realistic.

https://en.wikipedia.org/wiki/Loebner_Prize

by djmips 4 hours ago

Wow it feels like the Loebner prize went away right at the dawn of the LLM. Is it correlated?

by vunderba 3 hours ago

Yeah I definitely think LLMs contributed to its demise. To be honest, nobody in academic AI circles took it very seriously, because it kind of devolved into a contest over who could create the most convincing illusion of intelligence.

Participants spent more time polishing up the natural language parsing aspects in conjunction with pre‑programming elaborate backstories for their chatbot's bios among other psychological tricks. In the end, the whole competition was more impressive as a social engineering exercise, since the real goal kinda became: how can I trick people into thinking my chatbot is a human?

But reading through some of the previous competition chatbot transcripts still makes for fascinating reading.

I used to make my classes 60-80% project work, 40-80% quizzes all online.

I now do 50% project work, 50% in person quizzes, pencil on paper on page of notes.

I'm increasingly going to paper-driven workflows as well, becoming an expert with the department printer, printing computer science papers for students to read and annotate in class, etc.

Ironically, the traditional bureaucratic lag in university might actually help: we still have a lot of infrastructure for this sort of thing, and university degrees may actually signal competence-beyond-ai-prompting in the future.

We'll see.

by zamadatix 5 hours ago

I always preferred the "you get some grades along the way to gauge your progress but the lion's share of the weight went to the proctored exams" method unless the lion's share of the normal work was also proctored anyways (at which point it doesn't really matter how it's done).

The reason was less for myself and more because anything group related suddenly shot up in quality when the other individual work classmates were graded on couldn't be fudged.

by bee_rider 5 hours ago

The things I don’t like about putting too much weight in the exams are:

* It’s sort of unnecessarily high stakes for the students; a couple hours to determine your grade for many hours of studying.

* It’s pretty artificial in general; in “real life” you have the ability to go around online and look for sources. This puts a pretty low ceiling on the level of complexity you can actually throw at them.

by II2II 34 minutes ago

> It’s pretty artificial in general; in “real life” you have the ability to go around online and look for sources.

Sort of. In real life, you are expected to have immediate knowledge of your field and (in some environments) be able to perform under pressure. I'm not going to pretend the curriculum is a perfect match for what people should know, but it does provide a common baseline to be able to have a common point of reference when communicating with colleagues. I would suggest the most artificial thing about exams is the format.

> It’s sort of unnecessarily high stakes for the students; a couple hours to determine your grade for many hours of studying.

I don't like dismissing the ordeal of people who face test anxiety, but tests are not really high stakes. There is a potential that a person will have to repeat a course if it is a requirement for their degree. At least at the institutions I attended, the grade distribution across exams and assignments, combined with a late drop date, meant that failing a course was only an option if you choose it to be. A student may be forced to face some realities about their dedication/priorities, work habits, time management, interests, abilities, etc.. It may force a student to make some hard decisions about where they want their life to lead, but it does not bar them from success in life. And those are the worse case scenarios. A more typical scenario is that you end up with a lower GPA.

by acbart 4 hours ago

Exams happen all the time in real life. Or rather, situations where you can't just look up fundamental knowledge. Job interviews, presentations, even mundane work tasks - all these require you to know the basics quickly "The basics" are relative, of course, but I often point out to my students: "you don't care if your doctor needs to look up the specific interactions of your various meds. You do care if you see them googling 'what is an appendix'." Proctored, in-person exams are the only reliable mechanism we have for ascertaining if a specific individual has mastered key fundamentals and can answer relevant questions about them in a relatively timely fashion. Everything else is details and thresholds - how fast do you need to be able to recall, how deep, what details are fundamental. From there, I think it's fine to hate poorly made exams, and it's a given that many folks making exams have no idea what they're doing (or don't have the resources to do it right). But the premise of an exam is not completely divorced from reality.

by deepsun 4 hours ago

I think it's all about speed. In "real life" everything can be looked up, but exam optimizes to not even having to look it up. Then any research becomes much faster.

Whether it's good or bad I don't know, I think US higher education focuses too much on ability to produce huge amounts of mediocre work, but that's the idea behind exams.

by eichin 4 hours ago

One of the reasons I've always encouraged software people to learn to touch type has nothing to do with typing speed - it's about reducing/eliminating the cognitive load of typing, you want to be thinking in expressions (sentences) not letters. (The increase in effectiveness comes from not getting distracted by the mechanics of typing...)

by simpaticoder 4 hours ago

In real life you need to know the options and their trade-offs to solve a given problem. You don't need to know all the techniques perfectly, but you do need to be able to characterize them and compare them, from rote memory.

by acbart 4 hours ago

I agree, I think many people who rail against exams underestimate how important memory is to more complicated skills. How can you debug a complex application if you have to keep looking up every operator and keyword in the language you're using? It'd be like trying to interpret poetry in a foreign language but you have to look up every single noun. I'm not saying people can't do it, but it's tedious, slow, and you probably wouldn't think of them as a "professional worth paying for their service". Some amount of memorization is key.

High stakes artificial exams can help prepare you for artificial stakes at job interviews where you need to crank out a working solution in 30 mins with jet lag and someone looking over your shoulder

by ssl-3 3 hours ago

That's true. They do better-prepare an applicant for a job that filters on a person's ability to accomplish arbitrary things in a vacuum that is completely disconnected from the real world.

That's probably a good thing to filter on for, say, the navigation role on all kinds of crafts (from land to sea to space). There are naval roles where navigating with a sextant and memory is an important skill to have, and to test for.

But that operating-in-a-vacuum skill doesn't relate well to roles that don't need to exist in a vacuum. In most of the jobs in the real world, we get to use tools -- and when the tools go out to lunch, we don't revert to the Old Ways.

When an accountant's computer dies, they don't transition back to written arithmetic and paper ledgers. Instead, someone who fixes computers gets it going again, and they get back to work as soon as that's done.

by dublinstats 3 hours ago

Obviously they're both supposed to be proxy measures, not realistic scenarios. I was mostly joking before but I do think exams provide a pretty good proxy for ability in the subject if the teacher is decent. Interviews not so much unless the applicant is similarly prepared with foreknowledge of what they will be tested on and had some time to prepare and given recent practice.

by zamadatix 4 hours ago

This is where the alternative of a course with the other (still monitored for graded activities) option comes in. The downside of that tends to force in person synchronous rather than custom scheduling of regular tests.

The point is more about whether the graded work is actively reviewed than which individual choice is ideal or not though. Whether it's electronic or written, remote or in person, weighted towards exams vs continuous are all orthogonal debates to the problem of cheating/falsely claiming work.

I had attended a few courses over a decade ago and just completed a degree recently. The methods of cheating have changed, but not because of pencils vs keyboards.

by acbart 4 hours ago

So at 50%, someone who uses AI to get 100% of the homework grade will earn a D (sometimes passing) if they can get at least a 20% on your quizzes, and a C (always passing) if they get at least a 40%. Did you make your exam so difficult that students who truly didn't learn the material earn less than 20-40%? Because if it was, say, multiple choice questions with four possible answers, then you can expect them to earn at least 25% just by chance.

Why are people promoting the idea that exams are not written or given in person anymore? I graduated relatively recently and maybe had 1 take home exam during my entire education. Every other exam was proctored in person and written.

Things have changed drastically since COVID-19, at least in the US. Tons of schools and universities shifted to online systems, and never abandoned the systems they built up when it was time to go back to school.

I graduated in 2020, so I've only gotten to see the changes secondhand through friends and family who are teachers, and through my sibling who graduated a few years after me. But the difference is staggering.

by dublinstats 4 hours ago

Take home exams were very common when I was in school, which was before you could get answers on the internet. After internet answer and cheating sites came along, a professor would have to either not care and let cheating run rampant, or struggle to constantly make unique new kinds of take home questions somehow. AI has basically killed that option too.

I’d argue that dealing with any high criticality operational incident is like an in person exam (maybe even the most difficult kind, the open book one) if you are the one responsible for fixing it. Everyone is looking at you, you have time pressure to solve it ASAP and you can’t afford the time to dig through all the docs on the spot. So there’s at least some similarity with some real life situations.

by paulorlando an hour ago

I like this. Related, this semester I've been using handwritten quizzes in class. A simple change that's been one of the best things as it changed students' expectations of class prep. Kind of do the readings and sort of prep and you can coast in class. But if you need to write out quiz answers you're forced to know the material better as well as maintain the ability to express yourself.

I also use low-point bonus questions to test general knowledge (huge variation on subjects I thought everyone knew).

Context helps immensely, for example. Think of what you can do that someone outside tech can't.

by strogonoff 35 minutes ago

The “it does X for you” aspect of technology is not completely without its downsides, for various values of X.

For example, take “X” to be “walking”. Do we have the technology that allows us to pretty much never have to walk? Sure. As far as I am aware, though, we do not generally favour a lifestyle of being bound to a mobility aid by choice, and in fact we have found that not walking when able in the long run creates substantial well-being issues for a human. (Now, we have found ways to alleviate some of those issues for those who aren’t able, but clearly it is not sufficient because we still walk.)

The problem is exacerbated immensely as the value of X approaches something as fundamental to one’s humanity as “thinking”.

It does! That’s why you can ask to be evaluated by a commission of professors.

If you don’t pass after 3 tries, commission is mandatory.

You also have a paper trail of written exams and midterms to back you up. If you keep getting good grades and failing the oral, people will find that obviously suspicious.

Honestly the only times I had any trouble in the orals were the exams where I baaaaarely passed the written. Usually oral feels like the chill easy part compared to written because you can have a back-n-forth with the professor.

Still concerning from a statistical/psych fairness aspect.

There's a famous example of the Boston Symphony trying to fairly judge unseen applicants in 1952, and their results kept getting gender-skewed until they adjusted for the fact judges were reacting to the sound of shoes (e.g. high heels) when the candidate moved around behind the divider.

Uni professor here.

My colleagues that teach hard skills courses (like data structures and algorithms) either love AI and incorporate it into their teaching at every moment possible, or despise it in the same way graphing calculators were by high school math teachers when they were introduced nearly 30 years ago.

I teach soft skills classes to engineering students, and I'm unconcerned with students using AI. I write my problems in a way such that, if the student truly understands the assignment, prompting the AI to solve the problem and iterating on it takes a similar amount of time to doing the work themselves. AI is not very good at writing introspectively about the student. In other words, AI isn't going to be helpful when the homework question is "A fellow student comes to you asking for suggestions on how to maximize their chances at landing an internship. What advice do you give them that's immediately actionable?"

Try it, plug that into ChatGPT or your favorite LLM. It parrots the same generic tips everyone tells you, with very little on "how" do perform the action in an effective way. Read it, copy it into your advice document, get a poor grade. Try telling other students to take this advice. Note how they don't because the advice isn't actually actionable enough for them to take action.

LLMs are also not very good at the follow-up question "In a previous assignment you gave specific and actionable advice to a peer on the job search. Which of these suggestions were so good you are now doing them?" A number of students write a "Mental Gymnastics" essay, claiming they are following all their suggestions (because they think that's what the professor wants to hear) while the evidence they provide demonstrates they are not. A student asking an LLM to write the essay for them consistently produces a digital 'pat on the back'; a mental gymnastics essay that ultimately makes the student realize how unwilling they are to solve the #1 problem in their college career.

I've done away with exams wherever possible. I stick to project-heavy courses. What I've found to be far more concerning than AI use is the increasing loss of social skills and ability to cooperate within the younger generations. The number of students who would prefer to fail a class instead of talk to literally any human being is astounding.

The number of students who refuse to build soft skills, and believe that tech is truly a meritocracy where the only thing that matters is 'lines of code', there's no politics, and they won't work call or crunch or give code reviews, is also astounding.

If students cheat they hurt only themselves. Make sure they understand the consequences for cheating (missing out on learning) and that's about all you can do.

Depends on your measuring stick. Cheating themselves out of an education? Yep. Cheating themselves into a credential -> job - the status / remuneration of which is almost entirely divorced from the quality of the education, being aligned rather with the name of the organization on the diploma.

This statement is more defensible after removing “only”. If it “only” hurt the cheaters, there would be no need to police cheating at all.

The thing is, when colleges don't test students' ability properly before issuing a credential, employers start testing job applicants' ability after they've received it.

And they'll do it with all the 'unnecessarily high stakes' and 'risk of unconscious bias' and 'not truly representative' problems that written exams have; and a bunch of extra problems too.

This is untrue. Students who graduate without actually absorbing knowledge as laid out in the curriculum devalue the degree when they show up in the workforce lacking that knowledge. This is part of why new grads are undesirable job candidates, there’s a chance you are paying a higher wage for someone who may not have learned anything.

They hurt other students who worked hard for the degree. They hurt the reputation of the school and the utility of the degree as a credential.

When i attended university (almost a decade ago i guess, time flies) we didn't have a single exam on the computer. All exams were on paper or oral, most were without notes too. Computer science does not require computers.

by ButlerianJihad 4 hours ago

This is usually true, but it is also true that some classes are graded "on a curve" and so grade inflation could hurt people who are honestly doing work. Also, cheaters tend to suck all the air out of a room. For example, my I.T. instructor designed a really nice oral quiz slide-show for the entire classroom. I found it a few hours before the class, I watched it in its entirety, and then when he tried to run it live, I spoilered all the answers before any other student could answer. I wasn't strictly cheating, but I wasn't being fair to my classmates' learning process, either.

I had a typewriter growing up and I remember thinking it was the coolest thing. I was amazed by it and tried writing several stories. Eventually my dad bought me a crappy old computer that was only really good for writing, and that was cool too. I loved that thing. It was small too, with an integrated monitor and keyboard, so it didn't take over the whole desk where I still used pencil and paper often

Imagine being able to do some writing without notifications going off every few seconds, and where you're not always one click away from a search engine and some website scientifically designed to drag your attention down a rabbit hole and keep it there

Gyms aren't redundant because tractors exist.

by llbbdd 4 hours ago

Gyms are a great example actually because tractors exist to do the economically useful work. You now optionally go to the gym to benefit from fake labor that used to be the side effect of useful work. The fake labor is now what colleges are trying to sell, and it's going to kill them.

by Peritract 2 hours ago

Gyms predate tractors.

by llbbdd an hour ago

3,000 years ago, physical labor was a component of most jobs. Today gyms are for people who can afford to attend them and don't have a day job that naturally exercises them through labor. People exercising purely for health benefits, and not because the strength benefits them in their job and in other facets of their life, is new.

by onesociety2022 2 hours ago

Huh? The gym analogy doesn’t even make sense. People didn’t go to gyms when they were farming with oxen. Gyms are popular now precisely because tractors exist and you don’t need manual labor to farm anymore but people still need the physical exercise for their health. Society has adapted to the arrival of new life-changing technology. Our education system needs to adapt to new technology like AI too. You can probably uplevel a lot of courses and cover a lot more interesting topics than before and teach real application of things you learned aided by AI. Just like when I was doing a CS major 20 years ago, they didn’t spend too much time teaching me assembly programming beyond 1 or 2 lectures (they let me use a compiler for programming assignments!).

One consequence of LLM fraud at scale making remote/online tests & document submission worthless is it might act as a giant revitalizing boost for the bricks-and-mortars school systems. Suddenly having real teachers and students in room together has value again, for credibility and authenticity alone.

LLMs are also making having a public repo code portfolio be much more worthless as a sign of legitimacy

I’m confused about too many things being measured at once. Is Phelps banning AI to ensure her students are fit to pass terminal examination? And doing so to ensure that her class has a good pass rate, proving she is a good teacher and can keep her job? What if her cohort are particularly dumb? Is she incentivized to make it easy to pass her classes to get that A you paid so much for? Or hard or make that A worth something?

My mentor, a PhD in classics, told me it was never about outcomes and only about improvement. I suppose that answers my question. If your AI gets you an A at the start of the course and an A at the end, then, in the sense that you have not succeeded over anything, you have failed.

by PebblesRox 4 hours ago

My impression was she just brings the typewriters into class as a one-day novelty thing per course, not that it becomes the norm for the whole semester. The goal is to give the students a taste of what the old-fashioned way is like, to get them thinking about it.

I like open note exams (and perhaps open book exams, as you need to know the book well to know which page to look at) - it forces you to condense the material to the salient points and operationalise it to solve what would be more challenging problems than a simple recall exam.

When I see 'cheat sheets' - designed to be hidden on the back of calculators or whatever - then I see true application of human ingenuity and intellect.

This will only work until somebody figures out how to connect an AI to the typewriter which will have some sort of MIC, and the person will start dictating into it with AI-assisted revisions. Once the dictation is over, the AI-enabled typewriter will be instructed to type the work out.

Testing and instruction should be modified to account for AI. If a student uses an Agentic AI for work, learning, research, then when test time comes, the student should be required to stand in the front of the class and teach the class what they have learned, i.e. "Teach Back" all they learned to the entire class student body and teacher. The entire class, instructor included, will also be required to participate in a Q&A session to make sure that student's learning is not just made up of memorization, e.g. restate the information learned but using different words, different scenarios, etc.

Might be an unpopular opinion in this thread, but college was made worthless for most degrees as soon as the internet got popular and silly performative shit like this is the death knell. College is about learning how to work in an industry. I'd predict an uptick in trade schools and other hands-on work like medicine, and a continuing downturn in so-called formal education for anything white-collar, programming included. Students are customers. Businesses are going to use AI going forward. No reason to waste time on this.

Education is a nice side effect sometimes but yeah, I don't know how you could reach any other conclusion. If you're motivated to learn for learning's sake, college is an annoying slog that you know you don't need post-millenium. I literally left college early and started making money instead of spending it, because I got tired of demonstrating to my professors that I already knew everything they were teaching and that it'd be a waste of time for me to come to class.

by sarchertech 2 hours ago

Or maybe you chose to waste your time because you treated college as a way to get a piece paper instead of as the only time in your life when you are surrounded by experts who will spend an hour a week answering any questions you can think of.

by llbbdd an hour ago

No time wasted at all, that option is also trivially available outside of college, it's called "email". There's a whole industry in tricking new adults into believing that college is not about getting a piece of paper, it's gross, and it's avoidable. I paid off a year of unnecessary college debt in 1/4 of a year of doing real work I learned how to do in my free time. It's a trap and articles like this where colleges are working as hard they can to make education less useful prove it.

by sarchertech an hour ago

>No wasted time

You just said that it was a waste of time. So was it or not?

> that option is also trivially available outside of college, it's called “email”.

How many experts have you cold emailed over the years and how much of their time have you taken?

by llbbdd 15 minutes ago

It would have been more wasted time had I continued after a single year. I went to my first year of college on the advice of my well-meaning parents who are old and like most old people thought it was still important, and yet they agreed with my decision to leave after the first year on an offer for a real six-figure job because there was nothing to learn that I hadn't or couldn't have learned on my own. At least one of my own professors also openly wondered why I was there at all.

To your second question - less than a hundred, but tens. Most people who are worth listening to publish their work and their thoughts. Email is free. Experts love to answer questions about their work, professors hate doing extra work for no extra pay. The incentives here are not confusing. How much time have I taken? Confusing question. These are real people with real passion, and they answer questions with that in mind. Professors are obligated to puke up an answer. I've gotten responses in most cases, in some I haven't. When I don't get answers it's because the targets are smart and busy. If I wanted more engagement with my random questions I'd offer money, and if I had offered money every time I'd still be below par on the money I wasted on college. If I wanted to justify it - I'd say I learned enough to validate that paying real money for another 3-6 years would have been less valuable than burning it for heat.
