John Baez admitted, as early as in 2008, that Einstein's physics was going schizophrenic, and left the sinking ship:

John Baez: "Should I be thinking about quantum gravity? One of the big problems in physics - perhaps the biggest! - is figuring out how our two current best theories fit together. On the one hand we have the Standard Model, which tries to explain all the forces except gravity, and takes quantum mechanics into account. On the other hand we have General Relativity, which tries to explain gravity, and does not take quantum mechanics into account. Both theories seem to be more or less on the right track - but until we somehow fit them together, or completely discard one or both, our picture of the world will be deeply schizophrenic. [...] So, I eventually decided to quit working on quantum gravity." https://www.edge.org/response-detail/11356

If there is a next, Einstein-free version of fundamental physics, Einstein's 1905 nonsensical axiom

"The speed of light is constant"

will be replaced with the correct and easily justifiable axiom

"For a given emitter, the wavelength of light is constant".

I have developed the idea in a series of tweets he https://twitter.com/pentcho_valev
