Well, obviously nobody is going to mine undersea for the sake of mining undersea. If someone is going to go to the bother there must be some advantage that compensates for the difficulty. Maybe the ores are richer, or you don't have to dig as deep.
The ore is sitting right there, in coalesced lumps, on the floor for core green energy metals, and there's a general acceptance that the orders of magnitude involved over the next 3 decades require getting them.
I don't mind the discussion on it the past couple days, god knows wherever I get information from isn't the one blessed source, but I am worried about HN's instinctual "from first principles" reactions to undersea mining. Made me wince a little bit when I saw the post you're replying to say "I am always surprised when I find others don't just assume that undersea mining is more impactful."
I really appreciated you gently pointing out there's other smart humans on this and they likely have considered things like the environment.
