Honestly I think GPT-3's number one role in the next couple of years will be that of a muse. It's not really trustworthy as a direct source of info but it comes up with some really hilarious stuff and gets the brain working in new directions.
I don't know from a scientific perspective but it certainly feels that way.
I'd liken it to the results from Deep Dream style image generation. Each small part of the image makes sense but taken together it's a Lovecraftian nightmare that your brain can't quite process all at once.
