God help us, this looks like 4,000 years of human progress in a nutshell. We are forever waiting for experts and scholars to pass away so new ideas can be looked at and tested. Much of science has far more in common with an old boys club than with a quest for knowledge and truth.
Reality takes a backseat to politics and egos. It's more important that some specific individual is always held to be right than that anyone knows the truth. We do things backward and have unevidenced beliefs while wasting the planet's resources so as not to hurt someone's feelings. This is all despite the simple fact that everyone who has ever walked the earth is often wrong. No theory ever stands the test of time but it must stand the test of lifetimes.
What is wrong with this picture. Simply stated it's the silly, monstrous, and life defying superstition that we know everything and our scholars can't be wrong. We would literally rather die along with the entire race than be shown to be wrong no matter how wrong we actually are.
