Re: Touch screens
I often run my GPS when I'm going to places where I know the route, because I don't know the how the traffic and other conditions will change as I'm driving there. If there's an alternative route available, or I'm going to be delayed, I'm aware of it.
As for your old phone number, you know it because you probably had to dial it manually, and those of everyone else you wanted to call. You learned by repetition. Today the numbers are all in your phone's contacts, you put them in once and then you select them by name. Your phone hasn't reduced your memory capacity, people aren't getting more stupid - you're just not conducting the process that commits numbers to memory. I know my own phone number because I have to enter it on forms, the same reason I know my passport and NI numbers.
What people are still doing is talking bollocks about how the world is all going to hell and the latest new-fangled thing is making everyone stupid. They've probably been doing that since the first caveman started drawing on walls.
