It can depend on your exact definition of "broken", for example do you consider unpublished breaks resulting in "broken" or not? > RSA encryption is not broken by factoring keys but by exploiting implementation flaws. > Factoring a 2048-bit RSA key would require more energy than the world produces in a year, as explained here. The above should probably contain some caveat's like "Assuming a GNFS attacker, ..." or "ignoring hypothetical non-public mathematical breakthroughs"
