I disagree. It's really easy to increase key sizes (2048-bit, 4096-bit...) making brute forcing exponentially harder. Adding more GPUs in linear, same as increased speed.
Weak encryption (e.g. 512-bit RSA) can be cracked, and 1024-bit in theory (last I heard), but 2048-bit is still in the "not in the forseeable future".
The only way to change this is to create better algorithms, not faster hardware.
