If it hinged on that, then you would actually be saying it's impossible.
> The elements on Earth that make life possible couldn't have been created in a younger universe
Those statements also apply to the silicon and doping agents used in chip manufacture. They tell you nothing of relevance, we're not doing Carl Sagan's Apple Pie from scratch with AI, we're trying to get a thing like us.
"impossible with the approach OpenAI is using" != "impossible"
Eventually you need a whole universe capable of sustaining self reproducing intelligent systems. The way to get intelligent autonomous and sufficiently complex systems to do anything non trivial is life.
Anyone trying to sell you a box they say is capable of non trivial, adaptive, complex behavior autonomously is selling you a perpetual motion machine: a pretense that thermodynamics can be suspended at will.
All I am saying is that Sam Altman's promises (remember the original topic) hinge on breaking thermodynamics.
Humans evolved on a planet that was just so. The elements on Earth that make life possible couldn't have been created in a younger universe. So it take the full history of the universe to produce human intelligence. It also doesn't exist in a vacuum. Current human civilization is not a collection of 8 billion 20 watt boxes.
> As for human intelligence on a chip? Well, (1) it's been quite a long time since humans were capable of designing the circuits manually, given the feature size is now at the level where quantum mechanics must be accounted for or you get surprise tunnelling between gates; and (2) one of the things being automated is feature segmentation and labelling of neural micrographs, i.e. literally brain scanning: https://pubmed.ncbi.nlm.nih.gov/32619485/
I don't understand any of this so I won't comment.
