And in our modern world, universities are still the best place for such apprenticeship. Not the ones per Mark Trevor's words (https://marktarver.com/professor.html), of course, but a self-respecting university will train their students with progressively challenging and practical assignments. We started with implementing simple data structures and algorithms and solving simple puzzles all the way to implementing toy OSes, databases, persistent data structures, compilers, CPUs, discrete simulations, machine learning models. We started with implementing functions and individual components and quicly to building things from scratch. I'm forever grateful to the training I received in my univerity.

I spent a good portion of my life in Universities -- and went as far as one can go in terms of educational credentials and taught at the university level -- and I cannot disagree more.

Universities produce job skills incidentally, if at all. It's simply not their goal [1]. Even today, at the best CS programs in the country, it's possible to get a degree and still not be better than a very junior engineer at a software company (and quite a few graduates are worse).

This was not my experience, nor is it what I have seen in most university graduates. It's still quite possible for a CS grad to get a degree having only theoretical knowledge in these topics, and no actual ability to write code.

This leaves open the question of where "the best place" is to learn as-practiced programming [2], but I tend to agree with the root commenter that the best programmers come up through a de facto apprenticeship system, even if most of them spend time in universities along the way.

[1] Their goal is to produce professors. You may not realize this if you only went as far as the undergraduate diploma, but that is mostly what academics know, and so it is what they teach. The difference between the "best" CS programs and the others is that they have some professors with actual industry experience, but even then, most of them are academics through and through.

[2] Code academies suck in their own ways.

Having been self taught in both software and electrical engineering, I’ve experienced a lot of this.

In EE, it’s amazing how many graduates come into the job without ever having used Altium/KiCAD/Cadence for a nontrivial project or who can give you a very precise definition of impedance but don’t know how to break out an engineering calculator to set design rules for impedance controlled differential pairs. Or worse yet, people who can give you all the theory of switching model power supply but can’t read datasheets and select parts in practice.

Yeah the practical part is what does it. Students need time on their particular niche's software programs. Outside of Altium/KiCAD/Cadence there's also Mastercam, ANSYS HFSS, LTspice / SIMetrix/Keysight/CATIA/Synopsys/Dymola, among others.
I agree, however the model was clearly designed that the university considers first employment to be the apprenticeship and the university education to be rhetorical background education that makes it possible to follow and keep up in an apprenticeship. So really, the issue is companies don’t properly invest in training juniors… because they will leave after 2 years anyway… which is because they won’t provide them pay bumps equivalent to a change in position, which is also their fault, leading them to hire pricier individuals who just left another company looking for a pay bump instead. They pay the same in the end but trade individuals around pointlessly to do it, and have to retrain them on their software stack.

Kinda funny when you think about it.

I'll disagree with your "disagreement" - of course, I went to a relatively unique school: Waterloo computer engineering with co-op in the 90s. 8 study semesters, 6 work semesters. Clearly lets you see what "work" is like, and which parts of your studies seem relevant. Obviously, no one will use 100% of their engineering courses - they're designed to cover a lot of material but not specialize in anything.

True, grad school was focused on making professors - I did a master's, ended up being a lecturer for a while. Now a 20+ year software developer in the valley. But undergrad was focused on blending theoretical and practical skills. If they didn't, employers would have stopped coming back to hire co-op students, and would stop hiring the students at a high rate when they graduate.

I COULD have learned a lot of software myself - I was already coding in multiple languages before attending and had a side-software-contract before ever going in - and that was before the "web", so I had to buy and study books and magazines and I was able to do that reasonably well (IMHO).

Yet I never regretted my time in school. In fact, I had a job offer with my last employer before going back to grad school, and they hired me as a summer contractor at a very nice hourly rate back then.

Thank you for saying this clearly. I love universities. They are so far from supporting apprenticeships. Even phds — they don’t do enough work for the senior professors to count as apprenticeships. Maybe postdocs. But the system is not great—we need guilds.
Yea, I started to learn how to program in my early teens and made a lot of progress just messing around on my own. Then I went to University for a CSE degree and spent 4 years basically doing applied math. Yuck. Finally once I got out of University and into industry, I started learning again practical things like debugging, build systems, unit testing, application development, and so on. My programming skill growth quickly restarted.

Looking back, I'd consider my University degree to be essentially a 4 year pause on growing my programming skills.

I studied computer science in a university, not because I wanted to learn programming, but because I wanted to study computer science.

I admit that most development tasks don't need the knowledge you get from a CS degree, but some do.

But in computer science, it's also totally possible to be self-taught. I've learnt a lot on my own, especially after university. Computer science is good for that because it's generally accessible: you don't need an expensive lab or equipments, you can just practice at home on your laptop.

Polytechnic schools seem to do this well, research universities not so much.

I think it's important to differentiate the personal achievement of students and the training offered by their universities. For instance, the courses offered by CMU and MIT are super useful - insightful, practical, intense, and sufficiently deep. That said, it does not mean that every MIT/CMU graduate will reap the benefit of the courses, even though many will.

It goes without saying that it does NOT mean people can't teach themselves. I'm just saying universities offer a compelling alternative to training next gen of engineers.

I went to a good university with a decent CS program, and I'd definitely say I learned a lot more on the job than I did in school. I didn't always have any mentors to speak of but I did have at least a couple who were good.
I think both can true. I learned a lot in my university, and my learning has been carrying me ever since. Case in point, it was never a problem for me to pick up functional programming or programming-language concepts in general because the courses on programming languages were so wonderful. I had no problem tap into formal verifications or data science or distributed systems because my universities gave me solid fundamentals. Heck, I was not even a good student back then. It was Sam Toueg of the failure detector fame who taught us distributed systems, yet I was lost most of the time and I thought he was talking some abstract nonsense. Only after I graduated could I appreciate the framework of analyzing distributed systems that he taught us.

On the other hand, we certainly learned more after graduation (or something is wrong, right?). When I was in the AI course, the CS department was all about symbolic reasoning I didn't even know that Hinton was in the same department. I think what matters is the core training stayed with me and helped me learn new stuff year after year.

My own experience: https://www.quora.com/Could-online-coding-programs-and-codin...

And my wife's experience: https://www.quora.com/What-is-it-like-to-learn-computer-scie...

In short, the training that we got from our universities was invaluable, and I always feel fortunate and grateful to my CS department.

I'm self-taught and did pretty much all of those things. All it took was reading the docs.
I downvoted you because you are exceptional but the rest of the world is not. Most people benefit from traditional education, software engineering is not different.
its not THAT exceptional. I myself know several people who bootstrapped themselves into being descent software engineers. Traditional education is certainly fine for some people but its not the only way for the masses to learn. whats missing is the discipline of pushing yourself when you have no immediate extrinsic motivation.

You might have had a point a few decades ago when the information itself was difficult to fine but with the internet and online courses, its easier than ever to teach yourself in a "nontraditional" setting.

I was a self-taught software developer who already made money with programming for ~10 years before I took my first computer science classes.

Those classes unlocked a whole new level of programming for me. I just didn't know what I didn't know before.

People keep reinventing the same shit if they haven't learned about it before.

Sure, you can learn many things online. But for most things you just don't even know that they exist, you wouldn't know to search for them.

it only becomes exceptional after you start and continue doing it. I was not capable of self-learn before I applied to it.
I downvoted you because I kindly disagree. Seems like that's how you do it.
BS. Everything I learned from college was me anki and youtube. Lectures were wasting me time from actually studying. Most people I talked to they said. They didn't follow the lecturer at all just sat there like me for the attendence. There is no reason why we should continue to have mandatory lectures when you can just record them like Gilbert Strang did.
