...at least I don't think so:
You, too, will reach a point when a new gizmo seems impossible to use.
I could be wrong, but I don't think I am, considering the technological innovations we've seen in the last century. It's probably safe to say that previous generations either didn't really know what their progeny would be capable of or didn't think new inventions would make that much sense, and Froma Harrop tacitly acknowledges as much here. But with the newer technology comes a different mindset. Consider this:
Anyway, I told you all that to tell you this: We know what we're capable of. And I think it's safe to say that there won't be as many things that we won't be able to figure out as we think there might be. Back in the Depression a robotic car that drove itself seemed like a fantasy, but then the same could be said for laptop computers, the Internet and mp3 players. I really don't think we'll believe as our forebears did, that *fill-in-the-blank* is technologically infeasible. We know what we're capable of. And I think we'll adjust our mindsets accordingly to be able to take advantage of it. Thoughts? Borepatch? I was channeling you here somewhat...
