My daughter who is now 9 years old is just as excited as I was at that age when it comes to computers. We play with Microbit, Raspberry Pi and of course Minecraft. We also play code combat together, which is really an amazing and fun way to learn coding. Everything is on her promises, I never push her.
When I was 9 my dad did two things I'll never thank him enough for:
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.
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.
There were a whole bunch of parents in the US a few years back having their kids learn Mandarin because so much business was happening in China. I haven't heard this in the last few years though.
