yet bakers do not disappear. What's not valid about this example?
This seems relevant: "There isn’t a rule of economics that says better technology makes more, better jobs for horses. It sounds shockingly dumb to even say that out loud, but swap horses for humans and suddenly people think it sounds about right."
Except that it does not make sense at all.
Take 200 years ago, most folks were farmers. Take 100 years ago, there were now much more folks working somewhat qualified jobs (where they needed some actual skills) in industries. Take 50-60 years ago, with the creation of the service industries and all the jobs that came with it. And now for the past 30 years, hipsters are getting coding jobs and getting pretty good salaries despite the fact we have been living in a past century of technological revolutions.
And we are far, very far from 100% unemployment.
So your horse analogy has no ground in reality. For the most part, humans have been getting more, and better jobs on the whole, and most people commenting here are holding such higher paying, better jobs around. Thanks to technology.
The qualitative difference between now and 100 years ago is that those hipsters gave brains to the machines. The shift to service industries occured because machines replaced human muscle power. The hipsters started with replacing human precision, and now they're replacing human cognitive capabilities. Services sector is not safe.
It's also important to note what kinds of jobs are being created nowadays. A lot of them are "bullshit jobs" - make-believe work or elements of zero-sum-games like (big part of) advertising industry. Work has been disconnected from benefit it brings, we're literally (although usually indirectly) inventing nonsense tasks because we need to have something for people to do and not starve.
They transform. "Bakeries" become just a pick-up point, where you buy bread that was baked in scale (probably in industrial ovens) and delivered to the store. Bakery employees nowadays have less to do with baking than McDonald's employees with frying fries (they still do something to them).
