But at what price? Without knowing the exact position and velocity, we have no definite initial conditions. Without initial conditions, we have no predictions for the future. You've thrown out strict causality.
We've generalized it.
I refuse to be pushed by you into abandoning strict causality - not without putting up a harder fight than this. The thought that under certain circumstances an electron chooses freely in which direction it will jump is absolutely unbearable to me. If that's true, then I'd rather be a shoemaker, or ...
... Or a casino employee than a physicist. I think I'D rather have been a shoemaker if I had known how difficult it would be to convince you, Mr Einstein.
