I'm 41, I frequently have to remind myself of just how far tech has come in just the time I've been alive, especially when dealing with bewildered older people.

I'm 41, I frequently have to remind myself of just how far tech has come in just the time I've been alive, especially when dealing with bewildered older people. My first computer, the ZX Spectrum, was simple enough that we assembled and programmed a roughly equivalent machine from scratch on breadboard in my first year at uni. I recently resurrected my old Big Track robot/tank toy from my dads loft for my son to play with. Its over 30 years old, and has less computing power than an electric window controller, but back then it was the most futuristic thing I could imagine. My boy absolutely loves it. Its just the right level of sophistication for a 5yo, although I need to stick a volume control on it :)
