Some famous scientist — I wish I could remember who — said that new theories supplant old theories not on merit, but only when everyone who believed in the old theory has died.
Hence — don’t expect people to embrace your new idea. People hate new ideas. The good news is — eventually a new idea becomes an old idea.
Once people start to say, “Oh, that idea’s been around for a while,” or die, whichever comes first, they become more receptive to it.
