Earlier quoted context omitted.
It’s “low end” right up until you have no access to it. When it comes to national security, you don’t want to be in a position where the majority of your manufacturing output is at the mercy of a foreign country’s blessing. Your R&D is worth nothing if you can’t actually build.
That boat sailed a long, long time ago. The era where any country, even a giant like the US can make everything and be entirely self sufficient is long gone. What kind of future would realistically result in no access to foreign manufacturing or resources? If the risk is seen as China particularly, they only do the lowest value lowest skilled work. Pretty much by definition that's the easiest to relocate. Samsung doe…
This is a supply issue with silicon/electronics in general. At this point, it would be more of a disaster for any country to lose access to electronics than to oil. I'm not sure where you heard that manufacturing electronics is low skill, but I definitely don't agree.
The point is that there's no difference between the US and some country that has oil resources but no refining capacity. We can dig silicon out of the ground but we can't make anything with it.
The other thing you may be failing to consider is automation. If another economy gets there first, they won't be just building chips. If you're afraid of China becoming the fastest at bringing technology ideas to market, we are already there. And not just some ridiculously useless SV "x but for uber" product. A real piece of reality that turns on and can perform work.
This is even before you get into the national security argument about a trustable supply chain.
