I'd assume HN has a large percentage of neurodiverse people.

I didn't want to say it but yes, it feels like a large amount of the discourse I see on here is just people explaining things that are really obvious to me as a neurotypical person to people who seem to be autistic. I understand it's not really fair for me to complain about that, but it's naturally quite tiring to see constant explanations about the basic aspects of most humans.

I'd imagine you don't find the same in the world outside HN, so it probably evens out.

I welcome snark if it means engagement in the question: what “skills” are you advancing here? The skill to be able to solve a Rubik’s cube? Why?! Honestly: why.

I already said: because it's fun to improve your skills and also to compete with other humans. Rubik's cube is just one possible way to do this. Chess is another. Counter Strike is another. Running fast is another. Etc. etc.

Also: competeting with other humans is also a form of socialization. And most humans like that.

Same reason people climb Mt. Everest.

Why? Because the mountain is there. And it's a challenge.

Do you do anything for fun?
