Most of the hate is coming from people who don't really know anything about "AI" (LLM) Which makes sense, companies are marketing dumb gimmicks to people who don't need them and, after the novelty wore off, aren't terribly impressed by them.
But LLMs are absolutely going to be transformational in some areas. And in a few years they may very well become useful and usable as daily drivers on your phone etc, it's hard to say for sure. But both the hype and the hate are just kneejerk reactionary nonsense for the moment.
