Dude. Those factory workers just lost their jobs. Machines literally took their jobs. It's not a prediction, the article literally said it happened.

>So, have those doomsday scenarios come true? Or, instead, is the world a much much better place because nobody is spending 80 hours a week working on a farm to feed themselves?

I'd say that technology has benefited society but has also widened the wealth inequality gap. Technology has benefited us but it is now harder to be employed in jobs that distribute wealth more evenly. My guess in what is to come with technology is that there will be a few mega rich elite people who own that technological real estate while almost everyone else works multiple menial jobs to barely get by.
