Big if true.

Clicking around arXiv and google scholar, I get the sense the author is legitimate. But I wouldn't be surprised if some technical barrier was found by another expert. I don't think the author has published anything in complexity theory before, and the story of 'older academic attempts to enter new field with old tools, immediately solves most important problem in field' is a tad fishy to me, though not entirely without precedent. The idea sounds pretty cool though; I'd definitely prefer to be mistaken.
