As a random Internet commenter I can express an honest Ernest fervent hope that we'll solve cancer/etc and get fusion working on the next 5-10 years and there's no fraud. If I make that same claim while trying to get you to buy shares of my company at IPO that's a bit stickier. Companies making claims of wireless transmission of radio waves from NYC to London were sued for fraud, though one was ultimately successful at that. What material non-public information Dario has, we don't know. If he's sitting on information that makes it seem like it's not possible that is fraud. If he's sitting on tech that can simulate a human brain well enough to shorten the feedback loop in order to make that claim but doesn't want to make the claim publicly (GPU compute being semi-general purpose vs eg ASIC Bitcoin miners) that would be very exciting but if he's wildly guessing at the capabilities that AI could do in 5-10?years, that's another.
