My eldest son said recently that everything we really need had been invented by the 1970s. He will have no truck with social networking, refuses to text, and must be the only person on the planet who has asked (and been refused) a mobile downgrade (he now uses his wife's old mobile).
Having given this some thought, I think he has a point. I see my grandchildren glued to their little screens (when they're permitted; this son's children have very little of that kind of thing, and his eleven-year old is the only child in his class who hasn't a mobile); young mothers texting as they walk their children to school; people tweeting what they had for breakfast; ever faster and more sophisticated gadgets...and I wonder whether we need any of it. I know computers are useful (son has one as he has to have it for work), but we managed without them; we used to speak to each other and write to each other; proper conversations and real letters. We don't need to manage the whole house via a switch, which I gather is coming soon.
Meanwhile, everyone is "stressed" (why?), trains are filthy and crowded, meadows of wild flowers have vanished (probably beside the point, but still...)and no-one seems happy. So I've come round to thinking he's right. All the things I really need (washing machine, vacuum cleaner) were there long before 1970. Apart from a word processor (forget the computer; and I know I'm using one now, but that's because it's there), there's nothing post-1970 that I really need.
How about you?
