I like this nice little text. Einstein is a perfect example for mental liquidity. I think we should be very forgiving about this for two reasons: first, Einstein was one of the people establishing quantum mechanics. He also got the Nobel Price for his work on the photoelectric effect. Second, even the brightest minds have only a narrow time frame until mental ability starts to decline. So we cannot expect a brain to dig deep into general relativity and at the same time something completely different like QM. Surprisingly, Einstein even contributed to QM in old age by trying to poke holes into the theory that later proved to be true (e.g., spooky effects at a distance).
