You gotta wonder how Japan got such a corner on that stuff. A lot like China has a lock on the rare-earths, I guess.

China doesn't have a lock on rare earths. The ores are available in many
countries, including Australia. What China does more than anyone else
does is *process* the ore, because the processes are incredibly
polluting and they don't care about ****ing in their own pool. If they
ever tried to really restrict trade in rare earths you'd find plenty of
countries ramping up their processing programs.

Yeah, I love how some stuff is understated. Like when all those
lithium batteries in laptops were catching on fire. I read a report
where the burning batteries were described as "venting with flame".
