My cynical view is that it's mostly trade war and nationalism. If you follow the official PRC position, the chips are already made in China because TW is CN... Practically buying TW chips is boosting it's economy and hence funding it's military so from that perspective that makes sense. From long term development perspective this will absolutely boost national market... however that will take an insane amount of time. If you buy into AI is going to change everything hype, this move is a huge handicap and hence a boon to external economies. And I am probably missing a ton of viewpoints... politics meh

if you don't know what you're talking about you don't have to say anything, you know
