Okay i watched and listened to that. The professor does not say how these alleged bio-nano machines work, nor does he allege that they have built any in real life. He repeats your quoted line about 3 times and then moves on to things he actually knows about, which are teraherz communications and engineering (and nothing about biology). He spends most of the talk on problems with the technology, and what comes out is that it cannot transmit/receive much further than 1 metre (so it needs a massive mesh to retransmit packets) and would require a lot of new materials and equipment and network protocols that havent been built yet.
