only if the definition of success excludes having a stable, well paying position working for someone. I wrote some websites for fun at the age of 13, got into Linux at 12 but does anyone care? No, because that’s not commercial experience and that’s what matters in the world of job postings written mostly by non-technical people.

Nope. I only learned to use computers as an adult, and only learned programming incidentally as a tool for other work.

The truth is that it’s actually much faster to learn as an adult, you just have more momentum if you start as a child.
