And relying on GPS is bad for the brain, too.

An acquaintance offered to give me a lift to a party; she' d never been to the house before, so I asked her if she had a map. "Oh, we don't need a map, I've got GPS." We got thoroughly lost and finally had to pull over, call another partygoer, and ask her to show us the way.

A lot of people do seem to have an idiotic notion that the high-tech way is always the best way. Computers are only tools. Yet, in so many places, it seems that the tool has become more important than what you accomplish with.

I've even read a post (maybe on this blog) about the possible ethical problems involved in shutting down a robot. A robot is a machine. Recycling a robot is no more an ethical conundrum than smashing a can.
