Bans on Chinese open weight models being used in the US and bans on AI chips and semiconductor manufacturing equipment being exported to China are two extremely different things, and it's not inconsistent in any way to oppose one and endorse another.

is it export if they take control of the entire island manufacturing it.

banning export is short sighted and doesnt address any problem at a scale longer than months or maybe at most a few years.

> bans on AI chips and semiconductor manufacturing equipment being exported

In some ways, a ban on semiconductor manufacturing equipment exports is also a good way to keep the price of consumer electronics and other goods that depends on memory high because of the potentially decade+ long shortage of RAM we're looking at. I wonder how people here would explain to someone outside the tech bubble how it's good, actually, that those prices keep rising because it means we're preventing China from getting better at AI.
