If you can make an LLM solve a problem but from 100 different angles at the same time, that's worth something.
Besides, this would only apply for very few use cases. For a lot of basic customer care work, programming, quick research, I would say LLMs are already quite good without running it 100X.
Whatever is good enough now, can be much better for the same cost (time, computation, actual cost). People will always choose better over worse.
The compute/intelligence curve is not a straight line. It's probably more a curve that saturates, at like 70% of human intelligence. More compute still means more intelligence. But you'll never reach 100% human intelligence. It saturates way below that.
Thinking it will go beyond human limits is just wishful thinking at this point. There is no reason to believe it.
