It's even simple than that, IMHO. Yes, there are always new jobs to replace one you've lost to automation. But no, those new jobs are not for you, and not for your children. Someone else will be doing them - you will be dealing with the fallout of having your life upended, suddenly facing deep poverty.

You can re-skill - but you'll be competing for starter positions and starter salary with people who're just entering the workforce, much younger than you, with no dependents or health issues.

The technology may have benefited everyone in the long run, but in immediate terms, sudden shifts like these ruin lives of people, and destroy futures of their descendants.
