The important point when talking about AI and jobs isn't the susceptibility of specific jobs to AI, it's that all you have to do is have a sustained period of time where the rate of job elimination exceeds the rate of job creation. That's all it takes to destroy the fundamental functioning of any economy. If that happens, people won't have any money to pay all the plumbers, mechanics, etc. who still have jobs.

When that will happen, within a decade or within a human lifetime, is a matter of open debate, but it is almost inevitable that it will happen someday.
