The point is that at the moment we will replace all truck driving jobs in US, we are not going to replace 3.5 million individual workers, with skills that took a life to master, but 3.5 million jobs that a big slice of the 7 billion humans could learn to do in a couple of weeks (let's not start a debate about how far away we are from actually starting to have automatic trucks...). I don't see the point of feeling bad for these people loosing their jobs. As I don't feel bad for all the breakers that were put out of a job by the invention of air brakes (did you know that US railways took forever - and many casualties - to adopt air brakes, because they didn't want to fire breakers?) Reading and writing where a skill at some point. So was driving. But at this point, they are necessities (maybe not driving, if you live in a civilized country). We shouldn't keep jobs around just because some people really can't do anything else. I'm not saying that we shouldn't find a way for these people to live, but keeping them employed in jobs that hold humanity back, just because, is beyond stupid.
