Earlier quoted context omitted.

More that most undergrad colleges only teach and test regurgitation because the profs don't care about education.

I took the graduate version of this course, and thankfully did better on this exam than GPT-4. It was a fairly rigorous course, and getting an A required about 20 hours per week of work.

Of thinking or of remembering?

I'm curious how the predictive aspect of LLMs can generate / "solve" equations. Is it purely "these inputs are most likely followed by this output", and thus needs to have actually seen the problem to get it right, or is it able to infer some of the rules underlying the operations?

When I was growing up in the 2000s, it was required to learn a foreign language in school. I took Spanish but dropped the class after a year, thinking that when I grew up, computers would be able to translate text far better humans could. Would you believe it, transformers were invented ten years later. I wonder if it's worth learning anything anymore.

Machine translation isn't super human yet. But yes, it's probably only a few years away.

Doubt it … GPTs speak any language they know natively, but if asked for translations they seem unable to deal with sentence structures and logics that exists in the source but not allowed in the target language. When that happens they fail to recognize gibberishness of that.

Getting good enough that you can make a pun in a foreign language is almost entirely worth it, if you can spare the time.

If you wanted to learn Spanish specifically to get a job in language translation then sure, dropping it was likely the correct decision. Most people learn languages to, you know, actually speak with other people.

This is obviously very cool, but at this point — who knows what I’ll say in a year — my concern with these LLMs is that they’re in the uncanny valley. Here’s one passing a very difficult test. Amazing! Now, rely on it to build a nuclear doohickey for a power station or a multi-billion dollar device for CERN or anything really and, well, no. So humans still have to check the output, and now we’re in that situation whe…

Also today humans need to check the output, code reviews etc. Maybe in the near future humans can just focus on the reviewing and testing part.

Humans are going to want to do the worst parts of the job?

I agree with the point you're making here, but it’s also funny that the description of someone passing a test but not being able to do much without a lot of human supervision is… exactly the description of a human college graduate.

Can anyone answer the chance that example tests of these questions were in its training set?

And it's just regurgitating the answers someone else wrote?

As I imagine it's a very high chance given how much uni lecturers recycle exam questions.

When I was at uni you could just get the last 5 years worth of questions from the library for almost any subject and guess what the questions were probably going to be. Often they just changed a few numbers.

Teaching undergrads is like a sausage factory, the actual intellectual value for undergrads is in the seminars, the practical value in the labs. The rest is showing you can regurgitate what you've been told.

Which ChatGPT excels at.

Let me make an AI to check the first AIs work, then we can all have cake… on the beach… in Tahiti

>No negativity towards AI here. It’s amazing and it’ll change the future. But we need to be careful on the way.

Yeah, I suspect a lot of fields will have a similar trajectory to how AI has impacted radiology.

It might catch the tumor in 99.9999% of cases, better than any human doctor. But missing a malignant tumor 0.0001% of the time is unacceptable, because it spikes the hospital's malpractice costs. So every single scan still has to be reviewed manually by a doctor first, then by the AI as a fallback.

In theory there's some insurance scheme that could overcome this, but in practice when you have software reviewing millions of scans a day you're opening yourself up to class action lawsuits in a way no competent human doctor would.
