Except for the owners of the company, they get to pocket the difference...
But of course this is less about tech workers that are already getting outsourced because the, well, workers are more technically savvy anyway so of course it happened sooner.
It is possibly more relevant to people in management, or people like professors and many other random jobs who are discovering that working from home works fine for them. Though sometimes it's questionable whether this is because their work is largely on a computer or just because they didn't do much anyway...
If we don't have permanent UBI in place soon it will continue to be an emergency response to job losses like now. The economy is shifting as surely as the sun sets to one where if you don't own or play a major leadership role you either aren't necessary or can be outsourced.
Floor workers are getting replaced with robots and touchscreens; managers are realizing they too can be outsourced; lawyers are finding that no, the work they do isn't that hard to automate; doctors are finding that machine learning can analyze images better than they can; it's not going to stop... why would it? Why would a business owner want to keep a human with a continually increasing salary around if they can possibly replace you with technology that costs your annual salary once and after that just requires maintenance?
There are cases where that's just not possible, but my imagination for what is possible to swap has definitely gotten bigger. Even if a job isn't entirely replaceable, productivity tools are making the same amount of work take a quarter of the staff.
