The people next door beg to differ. Also big LLMs aren't the AI we will actually be using, it's small local LLMs. These data centers are a dead and everyone knows that, even the people building them, but not the people paying for them.
LLMs in general have a limited use, and are a dead end. So small local LLMs are also a dead end. That of course, does not stop people from using LLMs for purposes that they are not good at.
