  That's only 2 months for 900 pages, like 15 pages per day, it's impossible to read it so fast. IIRC checking the proof of the last Fermat theorem took a few years (and a few modifications to fix holes).

    I'd be unable to sleep worrying about whether one of my - should really be a +, or whether I stumbled on one step of "index gymnastics". Or I'd be wondering if someone would ever spot the deliberate <https://en.wikipedia.org/wiki/Beatosu_and_Goblu https://en.wikipedia.org/wiki/Beatosu_and_Goblu> trick of changing a single \mathrm{B} into a \mathfrak{B}. Or both. However, the authors are in close communication with many of the other authors in their extensive bibliography whose work this follows (and in turn who likely be provoked into further work). The progress (seen in the paper's review-like parts and the bibliography) has been towards proving that less and less "gentle" vacuum spacetimes aren't irrevocably upset by gravitational waves passing through them. The bibliography cites a number of pre-pandemic preprints that were in "to appear in <journal>" state. In that sort of academic bubble, which is far from unusual, errors are liable to be found fairly quickly. Also I would guess that the authors revisited their self-cited previous work, which sometimes produces forehead-smacking.

      My PhD thesis was in Harmonic Analysis and has a lot of Fourier transforms and antitransforms. I still think that approximately the 50% of the + or - signs are wrong. Anyway, in spite of the common image in popular culture, most math results are more roust and can survive a few sign changes, perhaps with some small fixes.
