I think there's perhaps a LOT of truth in it, rather then just some...
After reading that, it made me think about my past for clues.
As a kid (geesh, scarey just how many decades ago that was!
) I wasn't the smartest in Maths. The maths teacher at school didn't regard anybody not being good at maths as having the skills to program a computer - therefore only a small handful of "smart" kids got access to the schools Apple ]['s. So, a few months later and a years worth of pocket money savings got me a 1k ZX81 for $199, and it was all go from there once I made a point of being able to program to the teachers who seemed to suddenly pay more attention. As a psychological reason, I'd say that whole "I proved them wrong" thing made a big impact on my reasons for never throwing all that stuff away.
In the end, all those smart kids eventually spent more time playing sports outside while I sat in a dark room obsessively coding and learning machine code. You kinda wonder where peoples lives went after that - Mine never strayed from computing, though the last 20 have been spent focused in the 3D animation field rather then my initial "programming" career path I'd planned as a kid (though I did have a few programming/IT jobs as well along the way, just didn't end up being the main career focus).
So, maybe that's why I have never thrown away 30 years of history. Or I'm just a sad hoarder who can't throw anything away without feeling guilty. lol!
