Ask HN: Implications of Graphene discovery

So, Graphene transistors self-cool. Am I right in thinking that this is 'the discovery' that will be remembered as a turning point?

I mean, IIRC, CPUs are manufactured as (more or less) flat sheets because they can't handle the heat otherwise - if heat really is soon to be a solved problem, then we've open the door for CPUs to be dense cubes of transistors, and increased their ability by orders of magnitude...
