Ahh the myth of eternal technological unemployment. You realize that people have been saying similar stuff about every single piece of technology in the history of humanity, right? This is no different. There's always more work to be done.
That is not only generally false, but this time IS different. Since there is NOT always more work to be done, we have moved over to a service economy, where we CREATE more work to be done. BUT the software is now able to do many of those service jobs, and there's no other sector to move to. ALSO, every major technological advance HAS destroyed jobs, and some of those workers were left behind at every step. A lot of people DID become destitute, starve and even die due to the economic upheaval of the industrial revolution. If you want to invoke history and be taken seriously, you have to account for the parts you don't like, not just the parts you remember fondly.
Those service jobs were only viable because people had money, so as the percentage of service jobs has increased (it's now about 80%) the system has become more unbalanced because those jobs don't pay as well as more skilled jobs. (There may or may not be "unskilled" labor depending on who you ask, but there are definitely jobs which require more skill[s] than others.)
What industry do YOU think the low-talent service job employees are going to move into when there are no longer jobs for humans to read scripts on phones? When there are 10% or fewer jobs in fast food compared to now, because the work truly can be done by a bunch of robots plus one guy who knows how to clear jams in the burger printer and replace parts occasionally?
