>I'm sure some town in Italy wishes it was still the world's #1 diode manufacturer or something.

Except that's exactly what happened. EU semi fabs like the ones in Italy mostly make diodes, mosfets, microcontrollers and other such low margin products. Nobody here tapes out GPUs and CPUs, that's all Korea, Taiwan and US.

I wish more people understood this. Or perhaps they do, but it doesn't fir their political pitches or something.

Funding an enormously complicated semiconductor facility from a blank sheet of paper somewhere in Europe is a very expensive way to accomplish little, if the rest of the supply chain from materials to products is in non-friendly nations.

The way to bring in an industry the same way you do anything complicated: You start small. Get the specialized diode factory up and running again, and then build out supporting industries and value chains as needed. Complex lithography equipment can wait until last.

It wasn't long ago we built mobile phones in Europe. Ericsson, Nokia, Siemens, Alcatel and Bosch all had production and most if not all components were sourced from Europe or the US. Two decades ago is the blink of an eye in the larger scheme of things, not even a generation, and many who worked on this are still in their working years.

Without being directly related, it would also be a good opportunity to chisel out a crack in the Android/Apple monopoly. Then maybe in a decade or so you could actually live as a functioning citizen without giving remote root to the oligarchs and self proclaimed supranational kingmakers.
