If quantum entanglement "pissed off" Einstein, I can only imagine his reaction to this.
Now we have neutrinos that may travel faster than light. That would throw Special Relativity out the window, sure, but not the locality principle: those neutrino do not show infinite speed, unlike quantum entanglement under the Copenhagen interpretation.
To his deathbed he believed in his alternate explanation that the particles were set opposite "at birth" and initiated that way until observation (if I understand that correctly).
So now we have at least TWO phenomena that appear to be "faster than light" - so get cracking scientists (and engineers) on a practical application for communications to probes that are light-hours or light-years away.
