"The concepts of time (spacetime) in quantum theory and GR are thus drastically different and cannot both be fundamentally true."

So one is false but theoretical physicists would not discard it - rather, they reconcile it with the true one (in Big Brother's world theoreticians reconcile 2+2=5 and 2+2=4):
Natalie Wolchover: "The effort to unify quantum mechanics and general relativity means reconciling totally different notions of time. In quantum mechanics, time is universal and absolute; its steady ticks dictate the evolving entanglements between
particles. But in general relativity (Albert Einstein's theory of gravity), time is relative and dynamical, a dimension that's inextricably interwoven with directions X, Y and Z into a four-dimensional "space-time" fabric."

Perimeter Institute: "Quantum mechanics has one thing, time, which is absolute. But general relativity tells us that space and time are both dynamical so there is a big contradiction there. So the question is, can quantum gravity be formulated in a
context where quantum mechanics still has absolute time?"
