Today I took a trip to Guitar Center in a town an hour away to pick up a bass cab - our local Guitar Center was out of them. It's not a big town, but it's big enough to have a Guitar Center, and I halfway know my way around the town. But what I did, and what almost everyone does today, I plugged the address into a GPS, turned up Sirius XM's "Bluesville" station, and put the mind on autopilot. The GPS is saying "in one quarter miles turn left..." Not "turn south" but "turn left". Pre-GPS I would have relied on my inner compass, sense of direction, street direction, and so forth. I would have left the city with a greater understanding, and easier navigation for my next visit. Instead, I get "turn right and arrive at your destination", and I'm in the Guitar Center parking lot. I hadn't paid enough attention to know how to get home. I load up my bass cab, turn the GPS back on, and hit the "Take Me Home" button. The GPS takes me home on a different route. I couldn't find my way back there if I had to. But I don't have to find my way back - the satellites will watch over me.
There's no way I'd have believed this back in the seventies.
