A brute force attack on a randomly chosen AES key is impractical for the foreseeable future. With quantum computing some experts expect that a 128-bit key could be broken in our lifetime, but not a 256-bit key.

That said, plenty of systems using AES have been broken--using a secure block cipher does not magically make your system secure.
