I like sight as an invention, because I think having sensory perception and trying to comprehend the world, to use anthropocentric terms, is a really critical feature of life. And I also, it’s interesting the way that site has complexified over time. So if you think at the origin of life, nothing on the planet could see. So for a long time, life had no sight, and then photon receptors were invented. And then when multicellular evolved, those cells eventually grew into eyes and we had the multicellular eye. And then it’s interesting when you get to societies like human societies, that we invent even better technologies of seeing, like telescopes and microscopes, which allow us to see deeper into the universe or at smaller scales. So I think that’s pretty profound, the way that site has transformed the ability of life to literally see the reality in which it’s existing in. I think consciousness is also obviously deeply interesting. I’ve gotten kind of obsessed with octopus. They’re just so weird. And the fact that they evolved complex nervous systems kind of independently seems very alien. Yeah, there’s a lot of alien organisms.
