Reading about the horrific train crash in Spain that killed at least 80, and thinking back to the (rare) fatal airplane crash in San Francisco brought to mind the ride I took in a driverless car a few months back at Carnegie Mellon University. Many people still distrust a computer to get them from Point A to B. How long will it be before our thinking changes and we distrust humans to do the same? The train and plane crashes both appear to be due to human error, as are the vast majority of automobile crashes (which kill more than 1 million people worldwide each year).
I haven't spent all that much time in Spain but one of the most striking observations from a recent visit was how hard it is to buy a train ticket from a machine. In many cases, you have to wait in (long) line for a human ticket-seller. Whenever I asked why, I was told this was simply done to protect jobs -- an understandable, if unsatisfying, defense in a country with 27% unemployment.
It does make me wonder how much a country or culture with a strong sense of job protection will be resistant to technological changes purely on employment grounds, even if they might produce large gains for the greater good.
