There's a great 15 minute video by CGP Grey introducing the same set of concepts that technology will contribute to unemployment:

Its a bit pop-sciency, but its very approachable and well explained.
CGPGrey himself says the video is neither pessimistic nor optimistic: it's neutral. The video talks about something that has started happening and is almost certain to keep happening at ever faster paces.
It takes some effort to start thinking out of the box, seeing things from a much farther point of view and realize none of this is bad. The human race keeps advancing, progressing, and very often the leaps we make from decade to decade radically change the way our society functions. Cars changed society just as smartphones changed society. These changes force us to adapt and while sometimes it costs people their job, there just isn't that much room for these concerns, as cold as that may sound.
For example, digital distribution cost thousands of people their jobs in retail. Yet are we arguing digital distribution is a bad thing? Only those whose current income depends on the status quo not changing ever really make that point.
I haven't looked at the stats, but I'm certain that cars cost thousands of people in the horse industry their jobs as well.
This is very parallel to the "Would you sacrifice yourself to save 10 people?" moral question. In other words: "Would you sacrifice your own comfort to improve the lives of others?".
And I'm not judging. I've never been in the situation where I had to make the choice... but if I were, I would have very little actual input on the outcome. Nor should I.
In all fairness, most desk jobs that existed in the 50's and 60's are now heavily consolidated (it now takes one journalist and Google what it used to take 10 to do). And most factory work is either also heavily consolidated or moved overseas.
Would the words "service economy" even make sense back then?
And now there are headlines about automating low tier jobs in the legal and medical professions. The old refrain about getting a degree being a ticket to a steady income is long gone.
Never mind that the latest in assembly line robotics are as flexible as humans in their movement, and can be programmed by demonstrating the basic movements a few times. You can pretty much tell Joe to walk away from his station, and roll this robot into the same place.
Some simpler financial news articles are now written by zero journalists. A program just extracts numbers from data feeds and plugs them into a template.
Sports as well. You can't have journalists cover all lower league games, but an aide has to write a log about plays, which you can use to generate some metrics and generate something that fits roughly the right tone. (example that does advertise it: http://statsheet.com/ does this for basketball)
I'd be interested to see historical examples of any other kind. Human nature hasn't significantly changed over the past several millennia, as far as I can tell.
Its a bit pop-sciency, but its very approachable and well explained.
