Totally unproven expensive path, that places the ocean & climate at great risk (scraping the sea bed, emitting clouds of processes seabed that increase turbidity).<p>It would be remarkable to me to hear there's piles of neodymium or cobalt or bismuth just lying around. There's some metals yes, but this feels like it's not going to be a viable path to keeping us making jet engines, wind mills, and electric cars, not going to find all the needed elements. Its just pointless sound & fury, more sad destruction & anti-woke world burning.<p>This is so vile.
