Hi @julianhorack and @crypto.piotr
I have a different view on the subject. When I look at life I look at the process of evolution. The species evolved from previously existing species.
The new species were more adapt at facing the challenges thrown at them.
Even withing a give species with every new generation there is change and sign of evolution.
Coming to the topic of us humans right from birth we learn new skills, imbibe and evolve. So change and learning are part of evolution and there is no escape.
Had we not evolved we would be still hanging and jumping from trees and not having this discussion.

So whatever changes occur and whatever challenges our we as a species are fully adapt in dealing with it. Yes there would be new set of jobs that would evolve and so there would be opportunities to learn train our selves , get new skills and develop our brains further.
This is the positive side of the situation and I believe it is upto us to convert the challenges into opportunities.
