Ehhh. I get that exploitative techbros and cryptobros have confused the issue by latching onto the AI bubble.
But at the same time generalized artificial intelligence is very likely possible and will be an absolute game-changer if and when it happens. It's easily of similar value to fusion technology.
And it is already bringing truly impressive results into reality - protein folding and diagnostic medicine come to mind.
In the same way that computers are basically advanced abaci.
Don't confuse a simplification made to demonstrate the basic functioning to a layman with how things actually work.
LLM's are neural networks, which are based on a model of brain function. There's little reason to believe that we cannot eventually reach similar levels of effectiveness as human brains.
Hell - reaching the levels of pigeon brains would already be absurdly useful.
