I think we have a bubble in the US in government bonds, because of the quantitative easing and the negative real interest rates, and to some extent, that increases asset values across the board, including in startups.

There are quite a lot of people who think my aspirations are not possible. That's a good thing. We don't need to really worry about these people very much, because since they don't think it's possible they won't take us very seriously- and they will not actually try to stop us until it's too late.
