It's always made me curious why foreign governments allow their critical technical infrastructure to come from other nations - even friendly ones. It seems like something you obviously cannot allow yourself to become dependent on for a vast number of reasons.
Yes, the EU and it's member nations should invest heavily in their own domestic technical companies and capabilities.
However, I suspect part of the reason there is no present-day "FAANG" in the EU is in no small part due to their relatively anti-business/startup policies, which while well-intentioned, obviously have had a tangible impact on their tech business field.
Maybe some technical founders in the EU can chime in on some of the challenges they face when building within the EU versus the US.
