I disagree with this: "The previous one, the industrial revolution, created lots of jobs" That industrial revolution caused massive unemployment in India, in the Ottoman empire, in China... almost everywhere that had once been a famous textile center. The idea that the industrial revolution did not cause unemployment is an illusion that is caused by looking at only one nation state. But Britain was the winner of the…
It's not so much that the industrial revolution net created jobs -- like you, I'm not sure it did (even domestically).

Before it happened you had a much more distributed economy with many much smaller centers of production (many at the household level or close) in agriculture, trades, and craft manufacturing.

I guess what you mean is that the industrial revolution massively increased the amount of capital you needed to be able to produce goods competitively. Buying a set of tools and some raw materials to make things by hand stopped being a viable route out of the labor market into 'entrepreneurship' when mass machine-produced goods could be supplied more cheaply. Your option was to sell your labor to someone who owned some big machines, much like your ancestors sold theirs to people who owned a patch of fertile land, or a big pile of wood they wanted making into a ship.
So in a sense it created the modern labor market in that it locked a lot more people into it, and obviously diversified the kinds of jobs that existed. On the other hand, it was, as you say, a massive productivity multiplier which meant we were able to create more and more wonderful and complex goods for, in real terms, less and less cost, to the point where nowadays by exchanging your labor for cash, you can soon have enough money to afford a box of electronics that fits in your pocket and allows you to access all the world's information.
