It seems that way to me as well. I'm not a physicist but it seemed to do a very bad job yoking the research in question to the larger question of time. The research seems simple enough- gravity alone can't explain decoherence, and decoherence is a way that quantum mechanics is granted an arrow of time (other quantum processes can be run backwards indistinguishably). But the whole "time doesn't exist without an observer and observers create time" just seems to be begging the question. An observer with a brain has an arrow of time, because otherwise the brain doesn't have a past and can't make memories- how can you make a memory without an arrow of time? Observation seems to be an irreversible process. But brains are made of stuff, that stuff obeys the laws of physics, so where do observers come from in this theory?
