The corollary here is quite interesting: if we imagine this extending quite a ways into the future, we might ask what sort of society we'd like to live in far in the future, where more and more jobs are lost because technology makes them pointless for humans to do.

Say only 10% of humans had any skill whatsoever that would provide value that could not be more cheaply obtained by deploying technology. Say it got further, to 1%.

Imagine a world where only a handful of the most incredibly skilled humans can do anything better (i.e. more cost effectively) than a computer, and the rest are rightfully unemployed, because they have nothing to offer. A world where your 20 years of hard earned programming expertise is utterly worthless in the marketplace because an open source program exists that will read a plain language spec and spit out a good approximation of the same code you would have written, except without buffer overrun bugs and it'll be done in 20 seconds instead of three weeks. Where "lawyer" and "doctor" are professions-that-were because humans aren't fit to compete, and where one by one all the other careers considered unassailable today are swallowed up by increasingly sophisticated automation. Sure, we might be left with a few professions that require physical humanity (people will still want to see people in entertainment, for instance), but in the end, most of the wealth in the world will not be created by humans in any direct way.

You might start to understand why it's not such a terrible idea to move closer towards a socialist society as time goes on - eventually we're all going to be unskilled labor, possibly even unemployable, and we're close enough to that point (I'd say within a couple generations, at the outside, barring some major disruptions that hold back further technological progress) that we should probably start thinking about the consequences.
