The research looks detailed and interesting. However, I don't follow this summary article.
Digital circuits dissipate most of the energy charging and discharging capacitance. It must necessarily dissipate that as heat (except for a minor amount of electro-magnetic radiation). The interconnect resistance hardly matters. Of course RC relay can be a factor for some circuits. We can hope this reasearch leads to improvement there.
Power supply bus resistance can lead to voltage drops, but this research apparently studies layers much too thin for that application.

Did I missing something?
