Which ballpark are you playing in to come to a number like that? I have friends whom are authors, and they've certainly not seen a penny from Anthropic. I somehow doubt they're the only ones out there that haven't been compensated for having their work blatantly stolen. In a just world we'd be ensuring Anthropic was destroyed as a result of their actions, since their entire existence hinged on en-masse piracy.
(If, big if*) successful AGI will be such an accelerant to human thought, it should be able to reproduce every human work, every scientific theory, etc. without any training data, in a decade.
All we have ever done as humans is look at the world and ourselves, and then create new data out of what we've seen[0]. Now imagine how much parallel compute we could throw at doing the same thing.
