By intellectually understand, I just mean you can ask Claude or ChatGPT or whatever, "how can I recognize if a string is in a^n b^n? what is the language being described?" and it can easily tell you; if you were giving it an exam, it would pass.
(Of course, maybe you could argue that's a famous example in its training set and it's just regurgitating, but then you could try making modifications, asking other questions, etc, and the LLM would continue to respond sensibly. So to me it seems to understand...)
Or going back to the original Hofstadter article, "simple tests show that [machine translation is] a long way from real understanding"; I tried rerunning the first two of these simple tests today w/ Claude 3.5 Sonnet (new), and it absolutely nails them. So it seems to understand the text quite well.
Regarding computation and understanding: I just though it was interesting that you presented a true fact about the computational limitations of NNs, which could easily/naturally/temptingingly -- yet incorrectly (I think!) -- be extended into a statement about the limitations of understanding of NNs (whatever understanding means -- no technical definition that I know of, but still, it does mean something, right?).

Yes, well, that's the big confounder that has to be overcome by any claim of understanding (or reasoning etc) by LLMs, isn't it? They've seen so much stuff in training that it's very hard to know what they're simply reproducing from their corpus and what not. My opinion is that LLMs are statistical models of text and we can expect them to learn the surface statistical regularities of text in their corpus, which can be very powerful, but that's all. I don't see how they can learn "understanding" from text. The null hypothesis should be that they can't and, Sagan-like, we should expect to see extraordinary evidence before accepting they can. I do.

For humans it means something- because understanding is a property we assume humans have. Sometimes we use it metaphorically ("my program understands when the customer wants to change their pants") but in terms of computation... again I have no clue.
Personally I am convinced LLMs do have real understanding, because they seem to respond in interesting and thoughtfull ways to anything I care to talk to them about, well outside of any topic I would expect to be captured statistically! (Indeed, I often find it easier to get LLMs to understand me than many humans. :-)
There's also stuff like the Golden Gate Claude experiment and research @repligate shares on twitter, which again make me think understanding (as I conceive of it) is definitely there.
Now, are the conscious, feeling entities? That is a harder question to answer...
