> there's no AI. There are LLMs

Obviously AI is physically possible, unless you think there's something universally special about the earthbound naked ape's brain-goo that imbues it with special intelligence-stuff.

> the energy required to reach an ever increasing level of "intelligence" (or let us just call it pattern matching performance) quickly becomes so huge that it's simply not sustainable.

Every single human being has an existence (dis)proof inside their skull

> I think the current LLM approach is a dead-end bound to plateau not much higher than the current level. I'm not saying it's impossible to reach AI, but it would require a paradigm shift that I'm not even able to imagine at this level of available technology.
