Even online banking recently made a swap to 1024bit encryption; and even then,it's just a matter of recording the signal and processing it to get the passwords cracked over time,I suppose...

do not comment on something you have no idea about
:
1) Symmetric ciphers with 128bit keys are unbreakable by brute force and unless a major breakthrough (such as working quantum computers) is made, will remain unbreakable - possibly forever. Symmetric ciphers with 256bit keys will never get broken using brute force. There is not enough energy in the universe to do it, not enough time to wait for it.
2) What can (and occasionally does) happen is a break in the cipher algorithm itself. Given the amount of research into AES (and given the fact that even DES, almost 40 years old, is
still not broken), I wouldn't hold my breath. It is usually the various side channels that get broken (e.g. the key exchange mechanism in case of WPA).
3) Online banking has exactly
nothing to do with it: Key lengths in symmetric and assymetric ciphers are not easily comparable to each other; generally, you need perhaps 10 or more times longer keys for assymetric ciphers than for symmetric ciphers to achieve similar level of security.
