That's like saying the damage George Lucas has done to Star Wars is incalculable. Without George Lucas, there is no Star Wars. Did he fuck it up? Absolutely. Is the world a better place with Star Wars in it? I think so.

We're not going to change these old-timers. That's what makes them old-timers. We're only going to become old-timers ourselves someday (if we're lucky). Probably best to exercise as much compassion for them as we can, and hope the future returns the favor when our time comes.
