Most of my colleagues from the UK went through a similar curve, taking in Atari and Amiga machines at home not just as games machines but piqued by their capability to produce software of their own.
The UK 8-bit market was one of the biggest economic helpers the country has had in generations. We then went about squandering it.
Whilst I was a teenager the school curriculums moved to teaching PowerPoint and Excel which basically meant STEM entrants at University fell off. I was one of the last years to be able to learn how to code at school.
Detecting an impeding and urgent skills gap, a couple of years ago a proper computer science GCSE was kicked off (by the much maligned, but on this occasion perhaps quite right, Michael Gove MP), but only 11% of pupils in the UK sat it last year, and most schools are struggling to hire teachers so the quality of the kids they're turning out is a problem for us as a country and economy.
This is something I'm spending a lot of time thinking about right now. An open-source set of text books with teacher notes might help a lot of kids get exposure to the skills they need for the workplace in 30 years, the way I got exposure.
Yes, the RPi and microbits stuff is part of that, but there needs to be some steps beyond that. Kids need to be able to go home, look at the PC or laptop and think "I could make something on that", and get the guidance needed to do so.
