When I see an old movie, like from the ’40s or ’50s or ’60s, the people look so calm. They don’t have smartphones, they’re not looking at computer screens, they’re taking their time. They’ll sit in a chair and just stare off into space. I think some day we’ll find our way back to that garden of Eden.

What is the shape of space? Is it flat, or is it bent? Is it nicely laid out, or is it warped and shrunken? Is it finite, or is it infinite? Which of the following does space resemble more: (a) a sheet of paper, (b) an endless desert, (c) a soap bubble, (d) a doughnut, (e) an Escher drawing, (f) an ice cream cone, (g) the branches of a tree, or (h) a human body?

It's a waste to chase the pipe dream of a magical tiny theory that allows us to make quick and detailed calculations about the future. We can't predict and we can't control. To accept this can be a source of liberation and inner peace. We're part of the unfolding world, surfing the chaotic waves.

I think dry nanotechnology is probably a dead-end.

Our bodies are the time machine.

Intellectually, perspective [drawing] is a breakthrough, because here, for the first time, the physical space we live in is being depicted as ifit were an abstract, mathematical space. A less obvious innovation due to perspective is that here, for the first time, people are actually drawing pictures of infinities.

But how does it feel to plug into a system that's say, a million times as smart as a person.
