It happened before: computers, internet, smartphones, other machines were invented, productivity has only give up. And yet, we're still working 8 hours per day (and earning less than before).
AI will get people fired. More people need work = lower salaries, more profit.
It would be great if we could all just work less, but they won't let that happen.
So I'm guessing work use of a desktop is excluded?
Also, the article talks about "time spent online" and the map says "screen time", those are different things.
