I think job losses in the short term are possible (and job losses take place because of a bunch of different things, mind you), but I doubt they're massive in scale. That's just not how technology has been integrated into the economy thus far.
When new technologies are truly ground breaking, usually what you see is the early adopters gradually gaining an advantage over their competitors until those are either forced to change or go out of business, and that happens over a fairly long period. Kodak went bankrupt 20 years after consumer digital cameras first became available, for example. LAN centers are still a thing even though the vast majority of people have internet connections that can handle online gaming.
This theoretical mass layoff where a bunch of employers suddenly go "you're all fired, wellcome your new robot overlords" has just never happened. Like I mentioned before, the uniformity principle is flawed (just because something has never happened before doesn't mean it will never happen in the future), but it still leads me to ask for some VERY tangible evidence, like X technologies can be mass implemented as early as the year YYYY and will result in the direct loss of Z jobs.
