No, it wont because it's not going to scale from what I see and also will take a long time to develop over Ethereum. I don't see it being like Google any time soon but the hype would have people believe this.
Sure, in 10 years maybe, but there are going to be other projects which will have better more experienced development teams, built on better platforms than Ethereum, within that 10 years.
@dana-edwards I would agree with you.
