Space skepticism. Essentially, the idea that moving operations to space isn’t going to solve problems we face on earth. Not yet, anyway. Interesting for a few reasons:

1. How stuff works. From energy to communications to AI datacentres, it talks about what’s required to make them happen.
2. It’s a good case study into how bad we are at thinking about problems. Asteroid mining, for example, seems superficially sensible, but just red-penning the time taken to do it makes it instantly problematic, not least of which because by the time it got back to earth, the demand might have collapsed.
3. By examining what wouldn’t work, it also demonstrates what’s likely. Via negativa in action.

Fun.
