First, computing power is finite. The more work we require of them to learn our grandmother's recipe, the less resources they have available to learn our grandfather's favorite dirty joke.
"AES permits the use of 256-bit keys. Breaking a symmetric 256-bit key by brute force requires 2128 times more computational power than a 128-bit key. 50 supercomputers that could check a billion billion (1018) AES keys per second (if such a device could ever be made) would, in theory, require about 3×1051 years to exhaust the 256-bit key space."
Now, couple that with layered encryption (i.e. SSL over AES initiated from StartPage.com)... And what do you have? Security.
In other words. Your conclusions are simply wrong. But I am glad you brought up the subject.
