Not only that, each compromised table of passwords adds another set of new passwords to check to the databases that they use for cracking, which makes future cracking attempts faster as they have a larger set of known used passwords to choose from.
The rate at which passwords are being hacked is increasing faster than computing power because of refinements being made to the programs used to crack them such as this, and because of the uncovering effect as more passwords become known. As long as non-random passwords are being used, this will be an issue, which means as long as mankind will exist.
