The tech industry just got a lot more complicated. China has announced a ban on exports of rare earth metals to the United States, specifically gallium, germanium, antimony, and superhard materials. This move comes as retaliation to the US chip ban, and it’s sending ripples through the global technology supply chain.

Reading through various online discussions about this development, I’m struck by how many people are rushing to “future-proof” their tech purchases. While panic buying might seem like a logical response, the reality is more nuanced. These materials aren’t just about our gaming PCs and smartphones - they’re crucial components in military equipment, semiconductor manufacturing, and various critical technologies.
