Fish are probably constantly freaked out with all this new tech showing up in their neighborhoods.

Space travel has come a long way in the past few decades, but the people working on scuba and submarine technology are making the folks at NASA look like chumps. I had no idea half of this stuff existed - scuba scooters, personal mini-submarines, jet-propelled floating devices. NASA still looks stuck in the sixties compared to the tech renaissance going on underwater.

Half of this stuff was probably invented just to film Avatar 2, which is sad. But it’s all still cool to look at.
