What’s the regulatory path to something like this? Oceans seem to have all the problems of land except manifold: permitting is nigh impossible, and power is hard to line up.

To make it worse, underwater tech is notoriously hard to make operationally visible. Sabotage is trivial and undifferentiable from failure and honest error. When we used to work in trading subsea cable cuts in Asia would constantly ruin our best networks. Everyone had point to point microwave expressly because it wasn’t breakable in this way. Exposing compute to this rather than just networking would have doomed the entire enterprise.
