It happened before, and it was an issue back then as well.
Mundane job may be mundane (though note that it is sometimes subjective), but it earns someone bread and butter and it is always economic stress when the job is gone and many people have to retrain.
If we were to believe those of us who paint this technology as mind-bogglingly world-changing, that someone is now nearly everyone and unlike the previous time there is no list of jobs you could choose from (that would last longer than the time it takes to train).
If we were not to believe the hype, still: when those jobs got automated back then, people moved to jobs that are liable to be obsolete this time, except there is also just more people overall, so even purely in terms of numbers this seems to be a bigger event.
