Great quote from Jack Warner, founder of Warner Brothers, which I found on Marc Andreessen’s excellent blog (a blog I wish he had more time for). Warner was talking about movies, but I think — and I assume Marc agrees — that it applies to all kinds of things:
“Every worthwhile contribution to the advancement of motion pictures has been made over a howl of protest from the standpatters, whose favorite refrain has been, ‘You can’t do that.’ And when we hear that chorus now, we know we must be on the right track.”
The quote comes from Neal Gabler’s book An Empire of Their Own, about the rise of the Hollywood studios.
