Re: Isn't this going to make the chip shortage worse?
"The export ban is for tech used in _making_ chips"
Yes, but which chips? This ban might hamstring China w.r.t. it's production of state of the art cpus for high end computing (stuff at the 3 to 5 um lithographic limit). But that's a tiny part of the market. Most of which can be satisfied with 14 um microcontrollers. And they will still grab a huge chunk of worldwide sales, reducing the potential income of competitors who want such sales to support high end chip R&D.
