This is a short alert note! It looks like a new revolution in theoretical physics, involving Twistor concept, has been going on for some time. Spinor coordinates, Clifford Algebra and quantum states replacing the space-time and classical vector calculus. No longer are space and time the free coordinate variables of the quantum or classical equations of motion or of the curvature tensor (General Relativity - R.I.P.). No space, no time, no singularities, no Feynman diagrams, no locality, no 26 dimensions ...

For the most hardened, read this unreadable "Primer on Twistors" by Fedja Hadrovich.
