And we will probably continue to do so. Life expectancy in many countries is likely to rise so that further automation can help to keep the retirement age. Most people in Europe today retire at around the same age as 100 years ago (~65) while living much longer.

But still, we don't see joblessness or masses of people unqualified for the market. Faster developments will lead to many having 3-5 careers over their life time but I don't think that's necessarily a bad thing.

What's different this time is rather than replacing physical effort we are replacing judgement. Automated checkout lines, self driving cars etc are attacking the kind of jobs you can train people to do.

It's true we are creating more jobs, but mostly by having people do things that are low priority and thus low paying. There might be unlimited demand for service jobs like raft guides, but they pay crap because they compete with things like video games.

I only partly agree. We create jobs for both, high value added and low value added. The low value added still increase productivity (Amazon warehouse workers serve more clients than retail cashiers) but most focus will be on high value-added.

What disappears is the middle. This means we have to ensure that as many people as possible can get an education preparing them for higher value-added jobs. More diverse university courses and free education could help with that, vocational training can do the same.

Amazon warehouse workers are hardly the kind of jobs safe from automation. Self checkout lines supliment cashiers, but that means you end up with fewer cashiers in the short term not zero. Amazon clearly uses automation when cost effective and competing head to head with machines is not a long term viable option.
