Another aspect to consider is that a lot of the recent growth in AI is economic, not technological. The kind of language model that makes Hacker News headlines today is a thousand times larger than models were four years ago. GPUs haven't gotten a thousand times better, and the underlying algorithms aren't a thousand times better; companies are just spending a lot more money. There is no particular reason to expect that trend to continue indefinitely.
