Jup, Magdeburg will get a fab and I think TSMC is building one in the USA as well.

But Taiwan is currently supplying 90% of high end chips in the world. This will not be compensated for by a few new fabs (that are yet to be built). It's not like there won't be any new computer hardware, it's just that the supply/demand ratio will make them exorbitantly expensive.

Furthermore, to get a working part you need the other stuff too, like PCBs, capacitors, resistors, etc and a factory that combines all these parts into a working product. I'm not sure where exactly these factories are, but I'd reckon 90% are in south east Asia as well. So they may be heavily impacted as well.
