Should we eliminate the concept of reality?

I am following a general discussion on the probability function, because probability fascinates me from very early age. How the space between 1 and 0 collapses to one or the other? Apparently it is all an illusion because in fact it does not collapse.

Mathematician (pic)  Ulrich Mutze wrote: "I don't advocate to eliminate the concept of reality but we certainly have to modify it in an intelligent way that allows it to coexist with quantum mechanics." Is he aware of what he is saying? Modify reality? I hate metaphysics but is it the real thing while physics is just an illusion created by our imperfect senses? I shall never solve this thing.
