At their core, the state of the art LLMs can basically do any small to medium mental task better than I can or get so close to my level than I’ve found myself no longer thinking through things the long way. For example, if I want to run some napkin math on something, like I recently did some solar battery charge time estimates, an LLM can get to a plausible answer in seconds that would have taken me an hour.
So yeah, in many practical ways, LLMs are smarter than most people in most situations. They have not yet far surpassed all humans in all situations, and there are still some classes of reasoning problems that they seem to struggle with, but to a first order approximation, we do seem to be mostly there.
Exactly. I've used it to figure geometric problems for everyday things (carpentry), market sizing estimates for business ideas, etc. Very fast turnaround. All the doomers in this thread are just ignoring the amazing utility these models provide.
