I've seen it other places as well. Film/video post production has phases of the hot editor/colorist/director/etc. Then a new young hotness comes along because people feel the gray beards are too long in the tooth and impossible for them to be hip. Then the gray beards watch the newbie make the same mistakes over and over. It's called getting old. It's young thinking they are invincible and finding it impossible the olds can possibly know anything. It's human nature
