It's only powerful because they threw more cores at it than anyone else has previously attempted. From a quick skimming of the paper, there does not appear to be a lot of novel algorithmic contribution here. It's the same basic autoencoder that Hinton proposed years ago. They just added in some speed ups for many cores.
It's a great experiment though. You shouldn't detract from its legitimate contributions by making outlandish claims.
