I don't see myself as the king of Bitcoin. I don't want to be the king of Bitcoin.

Just as it got easier to use email, it will be easier to use Bitcoin as people invest in it and become more familiar with it.

In the future, I expect to see bitcoin mining in places where electricity is free or cheap. You could put solar array in the Arizona desert attached to bitcoin miners, and instead of trying to ship that electricity all over world, you could ship Bitcoin all over the world.

You really want some natural way for people to get Bitcoins, as part of their paycheck or some other activity so they can turn around and spend them. It's much better if the Bitcoin economy is a self-contained thing.

My salary is converted to bitcoin, and taxes are taken out. You have to do all the tax computations in dollars because the IRS does not deal in bitcoins.

Bitcoin as a globally distributed public ledger - that's the thing I'm most excited about going forward. Thinking about how to use Bitcoin in new and innovative ways. In the meantime, we have the boring uses of Bitcoin that are in the process of going mainstream.
