I'm not an introvert by any means, but I still choose whichever system is likely to work better.

At the supermarket, if I'm doing my monthly giant shopping trip and filling the car with non-perishables, I go through the attended checkout. Those people are quick and accurate, and there are two of them -- a checker and a bagger.

But if I only have one or two items, there's no line at the self-checkout, and I just throw the stuff into my backpack.

I wonder if a lack of class divisions is what encourages small talk in our society.

One thing about automated systems is that they have to work perfectly or they don't get used. I thought about this when taking the tram from the terminal to the parking facility at O'Hare Airport. I honestly don't know if the tram has a human driver or not. If that tram has a breakdown, it cause instant gridlock throughout the airport. And the way you make things work better (in the traditional quality control sense) is to make them more predictable.

And admittedly, I'm not shy, but I'm just a bit muddle-headed. With an app, I can see every detail of my request on the screen (and be looking at Google Maps on another screen maybe, or other information sources) before I click "accept." This makes it easier. But when I click "accept," I really don't care if the car that shows up has a human driver or not. I'm also pretty much oblivious as to whether it's a Mercedes or a Chevy.
