I agree that there will be many oportunities for higly skilled researchers and engineers and also a few jobs to train the machines too.
As if it will create more jobs than it destroy, this is another story.
To me this continue the long trend of many innovations to replace lot of repetitive, low value jobs by more advanced, complex jobs.
If we speak of a productivity gain though it still means this is less costly now to get the same than before. Either the highly skilled employee is actually paid less or he produce more, meaning you need less of them. This is more the second part I think.
Don’t ask if a productivity gain create jobs. it never does otherwise that’s not a productivity gain and nobody would invest in it.
It is something different that create new jobs. It is the new needs people create for themselves. But it would be enought that they value more to have some freetime instead of having more for all of this to stop.
When the new need was to get some food to eat or get a good health system, the motivation to work more was quite high. Now for many people in industrialized countries, this is more to get a new phone every years and a bigger house and they still work a lot for that.
May not last for ever.
