It's not about engineers vs. "Hollywood". I'm not even sure what either of those categories are, and I doubt the people who fall into those categories could agree who belongs in them and who doesn't. Also, the distinction is completely meaningless when you consider that many of the labor interests behind the "Hollywood" position are scientists and engineers who do the logistical grunt work of the on-screen magic.

Lose that false dichotomy and the rest of your post stands on its own: we won't win if we give up.
