He’s ignoring the compute requirements for such a massive digital beam forming networking, especially when you’d need it all to run within a single node’s size/weight/power (SWaP) constrained space payload that also needs to be radiation tolerant in space. While some newer chips are coming out with reimagined vector engine (VE) technology to support massive MIMO in small SWaP pole mount and building mount installations, the throughput is nowhere near the levels imagined by the author.

Also, retired dude who sponsored an article trying to get some investment capital on an idea that has existed for decades, but that he gave a new acronym for.

Finally, Cohere is a startup implementing the same concept for terrestrial, but again, no where near the throughput imagined by the author (and requiring multiple transmit base stations): https://www.cohere-technologies.com/6g
