"Schnorr has been making presentations on his concept since at least 2009. In my personal opinion, 11+ years is enough time for a small group to make some kind of significant demonstration software, if people believed that the idea is likely to work. Because this proposed factoring technique has been public for more than a decade, both specialists in lattice algorithms, and other mathematicians who focus on factoring algorithms in general, have had plenty of opportunity to study Schnorr’s ideas. I don’t see evidence that even one mathematician with relevant expertise has yet been persuaded." It's been out there for a long time and...nada.
