In what way do you consider that to be the case? IBM's Watson defeated actual human champions in Jeopardy in 2011. Both Walmart and McDonald's notably made large investments shortly after that on custom developed AI based on Watson for business modeling and lots of other major corporations did similar things. Yes subsidizing it for the masses is nice but given the impressive technology of Watson 15 years ago I have a hard time seeing how today's generative AI is science fiction. I'm not even sure that the SOTA models could even win Jeopardy today. Watson only hallucinated facts for one answer.
When Watson did that, everyone initially was very impressed, but later it felt more like it was just a slightly better search engine.
LLMs screw up a lot, sure, but Watson couldn't do code reviews, or help me learn a foreign language by critiquing my use of articles and declination and idiom, nor could it create an SVG of a pelican riding a bicycle, nor help millions of bored kids cheat on their homework by writing entire essays for them.
