It was obvious ten years ago that this was coming, but saying so just made you sound crazy.

I said a similar thing when the Nordstream pipeline was popped. Basically anyone with, say, $400k to rent a boat and a work class underwater ROV could have done it. Sure, pricey, but that's low enough that a single individual could have financed it.
