There is along way to go.
Yes, computing power is advancing at an astonishing rate, which probably wont slow any time soon. They are currently building a supercomputer that can recreate the synapses of a cat brain, ie, each transistor replicates one. But, guess what, it wont be as intelligent as a cat brain... cause of software.
Theres still along way to go, i would say on the software side of things - and i think thats going to be slower as things get more complex. ****, we still cant make cars that drive by themselves without hitting things. I think its great how people think we will be able to replicate a human brain in a few years, totally forgeting a little thing called conciousness that we still have no idea about...anyway.
As for power though, quantum computing has already seen proof of concept, so we might be seeing one of those 'trying' to power Crysis 11 in a few decades.
Oh and I bet out of all this 2012 BS, there is someone making a mint. I should start selling tickets to heaven on ebay...
