Is it realistic to stockpile specific chips, or does the industry move too fast for such a stockpile to be useful?
Then we'd have something to stockpile that wasn't a single source soon to be obsolete thing, and we'd solve a lot of right to repair issues.
We should be assuming that the whole tech industry is both fragile and a high value target not only in wartime, but by Kaczynski types, and also is even at risk of fading away and being forgotten at least partially.
It doesn't seem like much thought at all is going towards preventing the collapse.
