But back to your question. There are already rumors that NSA is using super fast traditional computers to calculate prime numbers and collect them in a database to make cracking traditional encryption easier.

The only thing I can think about with is is that for the NSA they are not moving quickly enough to catch up or they suspect any future quantum key encryption will thwart any attempts they made

RSA1024 is presumed to be breakable (was the default for decades), while RSA1280 (used by iMessage) is presumed to be near the limit of what an agency like NSA could break, and 2048 or 4096 is the medium term standard while long term it's either ECC or post quantum algorithms.

Today most of the cat and mouse game is about protocol design security and implementions. Just look at sidechannel attacks.
