> the ones who don't have mental capacity to work with models

Those people don't exist.

Sure they do - there are a lot of people who thrive working with concrete technologies and solve relatively straight forward issues (implement this component - style work).

These people will see a brutal job market that is forcing them to take more responsibility and work at a higher level of abstraction.

This is nothing new - A bunch of people simply don't thrive well as knowledge workers. The bar for being a knowledge worker is going to go up - by a lot.
