1. Buy me a laptop and install Ubuntu on it, instead of Windows, so my first OS was Linux. And I'm talking about 11-years-ago Linux for a 9yo kid.
2. Drill into me the importance of English. For non-English speakers, I believe this is the one true barrier of entry. All docs, forums, videos, etc. are English-first, and by the time they get translated into other languages it's no longer cutting-edge, so if you can't read English you are stuck with the "old" technologies.
Thanks, dad!
This. My parents don't really do IT and I wasn't old enough to pick it up from my grandfather, but both parents realised how important English is and made sure I spoke it already at a fairly young age. I'd never have been able to get into IT without it.
