> It was my (lay) impression that we believe general relativity cannot be the final fundemental theory of gravity because general relativity itself is not consistent with quantum mechanics.
That's the same as "not a quantum theory", which is what I was saying. "Consistent with quantum mechanics" requires "is a quantum theory", according to the many physicists I was referring to.
> Right now we have two separate theories (general relativity / quantum mechanics) that can't be combined because they conflict with each other.
Most physicists believe that they conflict, yes. But not all. Freeman Dyson, for example, has speculated that gravity might just be different and not require a quantum theory the way the other interactions do.
