Short, snarky version: Everyone should be shocked, SHOCKED! that general relativity doesn’t work where quantum theory is needed.
Matthew also rightly points out that framing a relativity experiment as a cult-of-personality exercise is a bad idea.
Newer theories supplant older ones conceptually, but every theory is provisional, constantly tested by experiments and observations. Einstein, important as he was in 20th-century physics, is not the ultimate authority even on his own theories, and refinements to his work should not be framed as proving him right or wrong.
