RSA cracked (to 22 bits)

So China has published a claim they've broken RSA. Sabine is on it. The comments are saying that they only got 22 bits so have some way before hitting 1998-era 256-bit, let alone what we're up to nowadays.

Longterm the better banks are pushing past 2048 bits to 4096 bits (which quantum probably won't reach); or are just plain using something else.

I expect no encryption is based on solving for high-order polynomials (bitcoin's not what we want them for). Last I heard the cryptobros were looking at stuff like "ECDC". That's elliptics, which aren't polynomial.
