These disorders - schizophrenia, Alzheimer's, depression, addiction - they not only steal our time to live, they change who we are.

Maybe we'll understand more about how the universe came to be, and what forces drove it in the early days and which forces drive it now.

It's actually kind of weird that we can comprehend the law of gravity, or that we can understand quantum mechanics, enough at least to make computers.

Behavioral economics can explain some things, but it's hard to explain a lot of the underlying processes that generate these decisions, much less some of these unconscious things that we don't have a handle on at all.

A lot of good ideas are actually bad ideas because, since they sound good, everybody's already doing them.

The brain is really hard to see. The whole thing is very large - the human brain is several pounds in weight - but the connections between brain cells, known as synapses, are really tiny. They're nanoscale in dimension. So if you want to see how the cells of the brain are connected in networks, you have to see those connections, those synapses.

I spend a lot of time going over old conversation summaries. A lot of the old ones are about ideas that ended in failure, the project didn't work. But hey, you know what? That was five years ago, and now computers are faster, or some new information has come along, the world is different. So we're able to reboot the project.
