As a kid in the 1970s and 1980s, I remember watching Jacques Cousteau on TV, and has work with the Conshelf habitats. I read the Undersea Trilogy by Frederik Pohl and Jack Williamson, with undersea cities.
Sea exploration and colonization was a big idea then, in no small part because of Cousteau.
But decade upon decade has shown just how hard it is. I don't think this new record will have much effect.
