Out-of-hand dismissal of Terence Tao is certainly a take.

And the term "artificial intelligence (AI)" has been the name of the field for 70 years and counting. If anything, "LLM" is a misnomer that's been lingering around since 2018-19. When the term was coined, these systems were relatively small, experimental, and could only produce impractical facsimiles of the English language. This is obviously no longer the case today.

"artificial intelligence" is a vague and moving target. I'm not sure I would call that "a field".

It's been used to talk about computers playing chess, then machine learning, and now LLM-based systems.
