See, the thing is that this is NOT a bad thing. 10,000 years ago, we could only travel at about 15km per hour. Now there are astronauts that go around earth and they travel that distance in less than 2 seconds. Technology allows us to either travel 7800 km in an hour, or 16 km in 2 seconds. In that sense when automation replaces jobs, it allows us to get the same work done in less time, or more work done during the same time. So in 50 years, lets say, we could do the same work that we do per person working just 1 hour per day, or do 8 times more work in 8 hours per day.
In that sense, technology and automation do not destroy jobs at all. The problem is how we organize society, not technology, we could still all be employed for 40h/week with 2% unemployment rate in 2100 if we, as society, choose to do more work during the same workshift. Or we could just work for half an hour per day and get the same level of comfort and work done than today. Of course in either case all jobs would shift towards higher level tasks, towards tasks that cannot be automated yet.
If productivity increases but average work per person does not, and at the same time we maintain a standard of 40 working hours per week, that is when unemployment rises. But as I have explained, those are a lot of ifs and it is just one possible path for society. Technology is not and will not rise unemployment, society's political decisions will.
