Hotz claims that Axios is reporting this but the only relevant article on Axios I could find [1] did not mention the cracking crypto part (or anything about polynomial time algorithms for factoring).

Big if true, but until we get some kind of official confirmation I will remain skeptical. I wouldn't put it past Hotz for this to be a troll for the lols.
