I think this is a disingenuous take.
Will AI of today definitely become AGI of tomorrow? No, for sure not, and anyone who claims this is at best crazy.
But is it imaginable? I think totally. Andrej Karpathy' blog post about RNN writing Shakespeare 1 character at a time was 10 years ago. GPT-2 was released 6 years ago. In that time we went from something that barely speaks English, never mind any other language, to something that, on a good run, is an excellent language tutor (natural and programming), can play games, can write moderately complex programs, goodness knows what else. For some people, the romance of a ChatGPT-4 was unmatched.
Even if it doesn't become "AGI", it might just get so good at being sub-AGI that the question is irrelevant. We're seriously contemplating a near future where junior devs are replaced by LLMs; and I write this as an AI sceptic who uses LLMs to write a lot of the kind of dumb code a junior dev might do instead.
I don't like AI, in that it nibbles away at my competitive advantage in life. But it's IMO crazy to pretend it is not even potentially a game changer.
