In 2018, on land and in space, preparations to deploy millions of antennas were very publicly being made and advertised, for “5G,” “Smart Cities,” and the “Internet of Things.” At the same time, and without any publicity, governments, research laboratories, and commercial and military interests were collaborating on plans to create “Smart Oceans” and the “Internet of Underwater Things” (IoUT). They did not consult the fishes, whales, dolphins, octopuses, and other inhabitants of those depths.
