Sports would also be much cheaper without humans.

The most important (if not entertaining) things you can do in space don't involve humans. Telescopes, communications, earth observation, sending probes to distant bodies, etc.

It's nice that we can send humans to space and it's good to keep that capability going so that the knowledge doesn't die. But the unmanned missions tend to pull the weight of actually accomplishing useful things. Humans just get in the way.

Turns out I don't understand the point sports either.
