We've had this same conversation since the start of the industrial revolution. Each time, people have insisted that this time it was different and sure to be the end of civilization. Famously, we called them Luddites.
As for predicting what jobs will be made available, that's a fool's errand. Nobody would have been able to accurately predict the many jobs we regularly do today. At one point, the expectation for the total number of programmers needed, across the globe, wasn't more than a few dozen. Yet, loom where we are today.
Back when I was young, in the 1960s, a common horror and science fiction trope was computers putting everyone out of work. The trope included such gems as the big brain eliminating entire office staffs and those people being unable to get work elsewhere.
The trope was so common that the first programmable computer I touched was called a calculator because HP didn't want the term computer to scare people away. This was the early 1970s.
Yet, with each stage of automation, we've improved our overall average lives and been able to make use of the excess labor for new and innovative tasks. I see no evidence, other than hysterics, that this is going to be any different.
If you want to keep people employed for no reason other than as an excuse to exchange money for labor, maybe you could just have them dig ditches? Holding back progress for the sake of keeping people employed is counterproductive. Automating tasks, making tasks simpler, is the point of technology and is what has afforded you to live the luxurious life you live when compared to the lives of people just a generation ago.
I'm not sure where the neo-Luddite trend has been coming from, but it has been strong for the past few years. If you want a suggestion, it is to embrace it and be at the forefront of it. It's not something you can prevent, legally or ethically.
Where, exactly, would you draw the lines? No more cars, because it puts furriers out of business? No more computers, because it puts human computers out of business? No more email, because it puts curriers out of business?
You live in a society created by the fruits of technology. You're happy to post your comment on HN instead of using the postal service or private currier.
