I would never say that's all we need, but... I do say that that might be the most important part we need! That is, language is the most distinctive feature our brains we have. DMN, and similar shallow "activity scans" don't tell us much. Yes, some animals have some kind of language, they communicate and predict trivial results or remember some events. But this is meaningless compared to the output of a human brain, the difference is abysmal.
I don't think there's anything interesting left in the bag.
