Well... you know, as a journalist-type piece, did you consider going out there and, you know, asking someone?
Because all the answers that leap to mind based on what I've seen out in the world in my circle of acquaintance, which (as I don't live in the valley) is not full of computer programmers, pretty much make the piece an entire waste of time because it fundamentally misses the mark. The people complaining about not having jobs and getting their hours cut are not people who are all well-to-do and just working because "what the heck else are they going to do?".
It also boggles my mind that one could write an article like this without examining the question of marginal value of time... if one is in the "leisure class" and has a job that pays $200/hour, when examining how much the person chooses to work one can't miss the fact that they have an option to make $200/hour. It shouldn't be that surprising that one might choose to work a bit more at that valuation.
