I have worked with a lot of junior engineers, and I’ll take comprehension any day. Developing their comprehension is a huge part of my responsibility to them and to the company. It’s pretty wasteful to take a human being with a functioning brain and ask them to churn out half understood code that works accidentally. I’m going to have to fix that eventually anyway, so why not get ahead of it and have them understand it so they can fix it instead of me?
For interns/junior engineers, the choice is: comprehension VS career.
And I won't be surprised if most of them will go with career now, and comprehension.. well thanks maybe tomorrow (or never).
