Stories like this always assume that the benefits of things like automation are equally shared. As if because business A saves X amount of money doing Y, they will divide that money up by the whole of society and just cut us a check. However, as we've seen, automating BART would now be done by a private company who would pocket all the profits. Pretending that this theoretical world where LaNesse does her hobbies is great seems to miss the point that she will join the ever growing ranks of Americans living in poverty. I don't even understand how statements like that are taken seriously.
Let alone distributing the benefits among mankind. For starters, you'd want the displaced ("obsoleted") workers to get a share of the benefits. You might ask why they deserve a share of the benefits when somebody else designed a system to replace their jobs... These are people who signed up for "risky" jobs, those which could be obsoleted within their working lifetimes. If we refuse to compensate them for that, we would face problems with people running away from any field which is "soon" to be automated, well before the jobs are actually automated. It's like asking them to hold the door open so someone could kick them out. To not compensate them (and hence ensure a smooth transition for everyone) would be tatamount to exploitation. It is interesting to note that a union of sorts will preserve employee interests in such a situation, by giving them bargaiing power.
