This is how places like the US despite having 4% of the population have about a quarter of the material and energy consumption. Not to single them out, I am in Australia, it is a similar ratio.
I am not defending this situation, just highlighting its role.
22nm is already overkill for a lot of applications. But, like, if your country gets embargoed, you should be able to make computer chips for cars and farming equipment. Top end GPUs? Not necessary. Some basic RISC-V cpu for compute appliances? That should be a capability that everybody has.
This part of why I have been advocating for years that the open source/free software folks should be focusing on optimization and stability/security as long term it will probably be much more useful that adding features that can be dumped on top.
The problem with bleeding-edge fab is it's a (fast) moving target. It's not a solved problem. And customers can't simply migrate their designs to a different fab, as the designs are increasingly specific to a process.
I do think we need more fabs but not this kind. Very low cost fabs with standardized PDK and open(ish) tools, should be as simple as ordering a PCB. Not going to happen anytime soon though, needs old fabs to stop production and the bleeding-edge to hit a hard wall. Can't compete with fully depreciated legacy fabs/nodes.
In case the first backup fails.
What are the chances that both a primary system and its backup would fail at the same time?
And for what?
