This may certainly be true of China, but the factory in question is located in Japan, which is an open market system like the US.
One of the limitations with all this technology is that it involves manufacturing processes that require very expensive and specialized equipment, clean room environments and other quality controls that make such factories very expensive to build, maintain and operate. It also takes a long time for these factories to come online. For these reasons there are not that many of them around, and collectively they shoulder the burden of supplying the entire world with the components they produce.
All it takes is one to go offline to throw off the entire world supply of those components. The real takeaway here is that as abundant as all this technology is in the marketplace, what most consumers don’t realize is just how fragile the infrastructure is to produce it.
The old line about “bombing a country back to the stone age” has more serious implications than one would think, because in a global market, it wouldn’t just affect one country, but the entire world.
