This will probably have metamaterial applications:
Fabrication of 3D fractal structures using nanoscale anisotropic etching of single crystalline silicon (free PDF)

The beginnings of molecular circuitry?

maybe, still have the heat problem to deal with but it looks like moore's law will stay valid a lot longer than expected.

the heat problem isn't the only impediment to moore's law.
and besides moore's law, there's also the von-nuemann bottleneck.

Did not the new Silicon-Carbide base material make a big leap for heat management?

I think there is some problems with finding materials with similar expansion coefficient to prevent delamination problems. but several solutions are in the works.
