I also remember decades ago people saying 'computers would take all our jobs'. They didn't - instead computers created new jobs - millions of them that never existed before the technology...
And earlier than that my mother commenting that the time before that most people worked directly for other people.. maids, cooks, yard workers, farm hands, cutting hair, delivering this and that... and that society wasn't that productive in the sense we now use the term. A few people had productive jobs and everyone else worked for them.
Interesting points Laz.
I think this is qualitatively different.
I think this is a society-changer at the same level as the invention of the wheel or the harnessing of fire.
