Gen Z here. I learned most of my basic computer skills by playing / modding games, editing videos, and having no friends. Gradually snowballed into writing scripts to make things easier, learning more programming languages and eventually getting books on more formal CS topics. I hope my kids can have a similar experience.

The ugly and maladjusted among us will always find a way ;)
