Okay so the thing I like about deep sea exploration, is that more or less we can send the billionaires there with a minimum of resources. The problem with launching them into space and letting nature take its course, is they're going to hover up so much of the planet's resources, and run over so many of our climate crisis mitigation attempts, that we all die.
So if you can figure out how to convince these fucker's that Gault's Gulch is actually at the bottom of the Marianas Trench, we might be in business here...
