Did anyone read the paper? I tried to, and it's a mess. There isn't nearly enough technical detail there to actually implement this system, and the incentives are so complex that game theory experts could be analyzing it for decades without finding all the potential issues. This is nothing like the Bitcoin white paper, which was very clear and complete.

Vitalik has created Ethereum of course, and he's not asking for investment, so this is better than your garden variety ICO scam. But right now this is more of a wishlist of desired features than a roadmap to implementation.
