If our brain is understanding some parts of the universe and not understanding other parts, and those understandings are about the laws of physics that our brains are built on top of, then it's kind of a loop, right?

It's not even known how many kinds of cells there are in the brain. If you were looking for a periodic table of the brain, there is no such thing. I really like to think of the brain as a computer.

I worry that we don't have a very good definition of consciousness yet which makes it hard to tackle.

Unlike optogenetics, where there are existing nonprofits that give away the DNA for free or at cost, expansion microscopy requires chemicals to be used, so having a company that makes the chemistry kit that anybody can use can save time.

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

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.

Suppose there are some things that we don't understand about the universe, but if you understand human intelligence and you understand the gaps in our abilities to think about things, maybe we can engineer in a computer more advanced intelligences that can help augment our ability to think.
