How many of you believe gravity cannot be quantized?

I know they've been working on this for a couple of decades. It seems it would hold the key to some of the deepest secrets of the universe. It's related to some of the most fundamental cosmic questions. I know they've been searching for gravity waves and the particle which would be the basis for the gravitational interaction. It appears to be a worthy work, but at this point, are there many who believe that gravity is not like the other fields? It doesn't operate as the result of a particle or wave. It's a fundamental effect of relativity. And as far as unifying all the "forces," with gravity, have they considered the possibility that it's an apples and oranges proposition? Are there many in the scientific community who are, (and have been), skeptical of this whole line of investigation and believe this kind of research is going down a blind alley?
