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.

There are many things that we still don't understand about the universe, right? Einstein struggled to bring quantum mechanics and gravity together and never succeeded, and that's a problem that to this day is not well understood. Well, maybe to comprehend some of these things, we need to augment our intelligence. If we do, who knows?

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 big part of my job is to remember failure, and reboot failure, when the timing is right.

If we succeed, it makes no sense to keep it only for ourselves.

For the last century of neuroscience, lots of people have tried to control neurons using all sorts of different technologies - pharmacology (drugs), electrical pulses, and so on. But none of these technologies are precise. With optogenetics, we can aim light at a single cell, or a set of cells, and turn just that set of cells on or off.

Work backward from your goal.
