Not OP, but I saw people wasting their lives on "big projects" that actually had little impact. (And that's if you're lucky enough to have it ship and not be cancelled.)

Imagine you are designing the McDonald's hamburger wrapper. "Oh, your work will be shown to millions of people!" And nobody really cares. I'd rather design something smaller that is truly appreciated.

it's absolutely this, and also, to go along with the analogy, feeling like "is McDonalds really a positive thing for the world? and why does it seem so verboten to express doubt about the absolute positivity of our mission?"
