This attitude reinforces the the problem. There are lots of jobs that are beneath people or just jobs. People still work them and do them well. Do they need to be excited and open about all their thoughts and feelings too? There's no reason a person can't hate to be put on the spot, hate to be interrogated by their boss every week, and still be improving their craft and planning to advance at the next jump.

You were super polite but you're pitching a one-dimensional view of engineers.
