Nice in theory but don’t know how practical it is to actually do.

How do you define “good”? Theres obvious examples at the extremes but a chasm of ambiguity between them.

How do you compute value? If an AI takes 200 million images to train, wait let me write that out to get a better sense of the number:

200,000,000

Then what is the value of 1 image to it? Is it worth the 3 hours of human labour time put into creating it? Is it worth 1 hour of human labour time? Even at minimum wage? No, right?

How do you stop people gaming this by feeding it the output of other AIs?

(not to mention defining "good")

You really think an OpenAI-sponsored social network is going to attract people who create and share original content?
