Work backward from your goal.

If you could map out a human brain, an open question is, if you simulated it, would it be you? Now, as we discussed earlier, we don't have a great definition or even a good technological handle to know whether something is conscious or not just by looking at it, so there's that aspect that we're not ready to answer, I would argue. But it raises very interesting questions about the nature of identity.

If you give somebody a lot of questions to answer and then they walk by a bowl of candy, they are more likely to grab the candy because they're tired out from answering questions and can't resist.

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

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.

Remember, when we're conscious of something, that state is quite often generated by unconscious processes that happen right before it.

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.
