To a limited degree, they can compensate for being such slow learners (by example) due to the transistors doing this learning being faster (by the wall clock) than biological synapses to the same degree to which you walk faster than continental drift. (Not a metaphor, it really is that scale difference).
However, this doesn't work on all domains. When there's not enough training data, when self-play isn't enough… well, this is why we don't have level-5 self-driving cars, just a whole bunch of anecdotes about various different self-driving cars that work for some people and don't work for other people: it didn't generalise, the edge cases are too many and it's too slow to learn from them.
So, are LLMs bad at… I dunno, making sure that all the references they use genuinely support the conclusions they make before declaring their task is complete, I think that's still a current failure mode… specifically because they're fundamentally different to us*, or because they are really slow learners?
* They *definitely are* fundamentally different to us, but is this causally why they make this kind of error?
Some machines, maybe. But attention-based LLMs aren't these machines.
The same way a todler creeping is the start of the general concept of space exploration.
But to your point, I do see a lot of people very emotionally and psychologically committed to pointing out how deeply magical humans are, and how impossible we are to replicate in silicon. We have a religion about ourselves; we truly do have main character syndrome. It's why we mistakenly thought the earth was at the center of the universe for eons. But even with that disproved, our self-importance remains boundless.
This a straw man, the question isn't if this is possible or not (this is an open question), it's about whether or not we are already here, and the answer is pretty straightforward: no we aren't. (And the current technology isn't going to bring us anywhere near that)
If you consider that LLMs have already "learned" more than any one human in this world is able to learn, and still make those mistakes, that suggests there may be something wrong with this approach...
