Tell me you know nothing about semiconductor design, fabrication, and manufacturing with out telling me you know nothing about semiconductor design, fabrication, and manufacturing

Rare earth metals aren’t rare. They are everywhere on earth. China just has the most easily accessible sources at the moment

China makes most of the silicon wafers that chips are made out of. Not because they're the only ones who can, but because they have the resources, infrastructure, and manpower to do it cheaper than anyone else. High end chips aren't manufactured in mainland China though. Taiwan, South Korea, and the US do most of that.

any place in the milky way

This is kind of hilarious phrasing because these metals are actually more abundant everywhere except for Earth because on earth where they sunk down to the core of the planet. inside of asteroids and things like that there's not enough gravity for that to happen.

Rare earth metals are actually pretty common everywhere else, China just cornered the market by having no environmental regulations, paying people to come into the United States and bitch whenever we make a rare earth facility because of environmental impacts, and using subsidy to undercut the rest of the world.

The moment trying to tries to block the world off where metal creation in the world will take off again.

In addition to knowing less than nothing about semiconductor design and manufacturing, you have no idea about elemental composition of objects in space.

“they have more rare earth metals than any place in the Milky Way”

Now at 11! Iron, nickel, platinum, iridium, and more just hanging out in our solar system? Meet 16 Psyche! The dense, metal rich asteroid that has potential to supply the world with rare earth elements!

The Milky Way is a very, very large place my friend, there is an almost guaranteed certainty there is another body with a far higher concentration of what we call rare earth elements than China or the entirety of Earth itself.
