When you sit down and think about it, a time machine is a pretty useless idea, right now.
You can visit the past any time you like, usually within a few minutes’ walk. It’s all around you. As for visiting people in the past, why bother? They’re no different than the people you have around you today...And as far as the “interesting” people back in the year dot, there’s plenty of interesting people around you right now, if you’d just take a minute to get to know them.
As for living like it’s the past, shut off your computer and read a book. Leave the car in the drive and go for a walk. It’s really just that easy.
And the future, well, the future will be on your doorstep soon enough, all sticky with blood and ashen with fear, all 10+ billion of them wondering where dinner is. No, the future isn’t worth considering, time machine-wise, because you’re already going there, at a rate of one minute per minute.
As for living in the future, you’re already doing it. You have amenities and conveniences that were never even imagined back in 1980...Let alone 1900. It used to take 6 weeks to get a photograph to England...Now I can take a picture with my phone and send it anywhere in the world, total time elapsed being about 30 seconds.
We are all living in a science fiction novel, each and every one of us. We’ve managed to avoid all the really dismal predictions, like eating pills instead of real food (Why did anyone ever think food pills were a good idea?), “welfare islands”, and robots all over the damn place...Instead, we’ve managed to build a paradise of information gizmos and conveniences - the fact that it is a fool’s paradise notwithstanding - and we have no appreciation for it. The very fact that you take reading this for granted is all the proof required to demonstrate this.
So instead of yearning for a past that wasn’t as cool as we’d like to think, or ignoring what’s happening today in favor of what might happen tomorrow (as the “transhumanists” do), perhaps we’d be better off exploring the world that we actually have, and getting to know the people that already surround us.
Okay for now,
