2. Theories that need theories are the luckiest theories in the void.

From the article:

"We have shown that if spacetime doesn't have a quantum nature, then there must be random fluctuations in the curvature of spacetime, which have a particular signature that can be verified experimentally," he added.

"In both quantum gravity and classical gravity, spacetime must be undergoing violent and random fluctuations all around us, but on a scale which we haven't yet been able to detect. But if spacetime is classical, the fluctuations have to be larger than a certain scale, and this scale can be determined by another experiment where we test how long we can put a heavy atom in superposition* of being in two different locations," Weller-Davies explained.

We may be overthinking this on the cosmic scale. Like when observing sub-atomic particles, it may be the human brain is not built to think about the cosmos without changing the cosmos itself.
