I think we are talking about a different job. I mentioned it somewhere else, but strapping together piles of bot generated code and having to debug that will feel more like a burden for most I fear.
If a programmer wanted to operate on a level where "value delivering" and "impact" are the most critical criteria for job satisfaction, one would be better of in a product management or even project management role. A good programmer will care a lot about her product, but she still might derive the most joy out of having it build mostly by herself.
I think that most passionate programmers want to build something by themselves. If api mashups are already not fun enough for them, I doubt that herding a bunch of code generators will bring that spark of joy.
Most programmers are working in business-focused jobs. I don't think many of us, in grade school, said "I sure hope I can program business logic all day when I grow up." So I think the passion for 90% of people writing code is really about getting a paycheck. Then they use that paycheck to do what they're really passionate about in their personal life.
So I completely agree that people passionate about coding might want to write that code by hand, I just don't think that group accounts for most people writing code professionally.
