It's interesting that you say that. Recently I went on a trip where I had my phone and I was largely in urban environments, but I spent lots of time (most of each day) just walking around cities and looking around. I felt so calm and balanced, even though there was tons of noise and traffic and things I might assume would induce stress. Garbage collection of social objects is an interesting way to put that phenomenon.

It’s all just recursive computation and memoization of the important bits.
