A rather shallow analysis. He first asserts (he doesn't explain) how fundamental limits to further miniaturization of silicon devices are based in heat (the chip would melt itself) and leakage (due to quantum principles electrons won't stay localized in such small features - "can't say anymore if an electron is in the chip or outside the chip").
Then he moves on to mention molecular circuitry whereby current flows through a molecule instead of only through metals and silicon - but he never explains why the above two fundamental problems wouldn't apply to molecular circuits. It's not like organic molecules are more thermally stable than metals and silicon, or that they are bigger than patterned silicon features.
What a waste of time.
