We can, in fact, get a low energy effective field theory for quantized general relativity (that’s a mouthful). But I think this is a case of physicists talking past each other. When we say that GR and QM are incompatible, we tend to have their physical content in mind.

The low energy EFT is just classical gravity as a background field

Yeah, that’s one of the pieces of ‘physical content’ I had in mind. Background independence is very rich in substance, and simply applying quantization methods successfully doesn’t make the problem go away.

Yeah Donoghue is exactly who I had in mind. I really enjoy his stuff but I think this one part isn’t handled too carefully lol

i'm giving it a read now

Burgess has some really good (but I doubt you have the time to do more than skim) notes: https://arxiv.org/abs/gr-qc/0311082 … Planning to use some of his stuff when I finally get some physics for philosophers entries going lol

I like donahue's overview of EFT.. nice and succinct
