Our understanding of the world is so advanced that revolutionary changes are bound to be rarer and when they do happen they're understood by a tiny fraction of the population. In fact most people have absolutely no idea what Einstein did. He was indeed a great scientist, but to the average person Einstein is a just an idea of a genius, they were never touched by his work. I studied physics in undergrad and I barely understand anything about GR, though i have some understanding of the historical context so i guess that gives me a bit of appreciation for what he did
