This is one of the reasons there should simply be a big tax on AI profits, assuming they come to pass: they literally require uncompensated training on the sum of human intellectual effort. There is no AI without standing on the shoulders of both giants and thousands of everyday authors.

If you're just giving the result back to humanity, OK, there's a case for it being a fair trade, though there's still the question of how to handle the disruption of long tradition of valuing & compensating labor.

If you're using it to win capitalism, 50% tax seems starting stakes. Sure, lots of expertise and resources go into the data processing to produce a model that can talk to you, but without the data, the processing doesn't matter (and without the model, we could still do this collectively).
