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

We don't have a "consciousness meter" that'll tell us exactly how conscious something is. I think we might get there eventually.

If you think backwards from a big problem, and you talk to all these other people who have skills and who think forward from their skills, it's very easy to form collaborations because everyone is incentivized to work together.

It's surprising that the world is understandable to the extent that it is.

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.
