There are really two things that have to occur in order for a new technology to be affordable to the mass market. One is you need economies of scale. The other is you need to iterate on the design. You need to go through a few versions.

If you think back to the beginning of cell phones, laptops or really any new technology, it's always expensive.

I'm interested in things that change the world or that affect the future and wondrous, new technology where you see it, and you're like, 'Wow, how did that even happen? How is that possible?'

Physics is really figuring out how to discover new things that are counterintuitive, like quantum mechanics. It's really counterintuitive.

I think the high-tech industry is used to developing new things very quickly. It's the Silicon Valley way of doing business: You either move very quickly and you work hard to improve your product technology, or you get destroyed by some other company.

Government isn't that good at rapid advancement of technology. It tends to be better at funding basic research. To have things take off, you've got to have commercial companies do it.
