Assuming for a minute, hypothetically, that the NSA can crack AES and RSA, then the way to combat that is for more people to use it more often, and to create me

Assuming for a minute, hypothetically, that the NSA can crack AES and RSA, then the way to combat that is for more people to use it more often, and to create meaningless encrypted spam. Cracking requires huge computing resources. If there's an overwhelming amount of data to crack, with little guarantee of any useful yield, then we can reasonably expect it that negates the ability to crack it.
