It's a very wide mix of explanations about computation, biology, physics, creativity, politics, and philosophy. The explanations are pretty deep, so they explain an infinite number of phenomena. So they stand at the beginning of infinity.

The book resolved many questions for me. For example:

What is optimism?
How much a human can understand?
How far we can go exploring the Universe?
How to make a successful meme?
Why don't we have AI yet?
Can the political system ever be fair?
* Is dark forest theory real?

The explanations are not ideal, that's for sure. But it's something.

The first and several last chapters are safe to skip, but the rest is golden.
