I have close the zero faith that the EU would be able to make the cultural changes necessary to move to self dependance.
Especially with being well behind in the current AI arms race. You need the opposite of a "workers utopia" to do all the things the EU needs to do, and do them fast.
They either stay with the US or become a vassal of Xi Jinpeng.
you dont really need to get involved in the ai arms race though. a late comer will still benefit from better designed at higher volume lower energy chips, and good enough open weight models.
