I wish people would stop generating stuff they don't understand only to forward it to someone who does. Something about that really rubs me the wrong way.
Lol. If Gowers sends you a piece of math he doesn't quite understand because he thinks that you might, that is something you celebrate.
May I remind you that this is Timothy Gowers. He says he doesn't understand, but he most certainly has far greater capacity than most to detect complete junk from a maybe plausible argument. His colleague is even better able to judge this, hence why he sent it to him.
Also if he did send me complete junk, I would still parse it for multiple days to see what is there.
