You know there is this movement called open source software right?
With it not only a lot of strategical pieces of software are available to anyone to modify, but it also allowed people all over the world to contribute to them.
This means that not only Europe but other parts of the world have people with enough knowledge to not only contribute, combine and use those things but also to 'push the envelope' in research and development.
BTW, a more decentralized, organic tech world, is something we should try to achieve, because as we are seeing now, there are no safe heavens for anything, anymore.
We should think more like human beings and less with nationalistic mentality, because all i've seeing til now, is nationalistic values being use not just to undermine other countries, but also undermine the nationalistic's own country.
If there's one valuable lesson history teach us, is that even the Rome empire, comparatively much powerful than anything we have now, started to fall when they corrupted the core values that served as a foundation of the Roman empire.
And nationalistic, the "we are better than everyone else", walls, stupid wars, etc..
But lets not forget an important difference here, right now all the achievements, the culture, the universities, the internet, the knowledge is widespread all over the world..
This is a pandora box effect, that once opened, cannot be closed anymore.
So even if the US totally closed itself to the world, im pretty sure the world would keep moving forward, and once this Donald Trump version of US lost it all and tried to become part of the world again, im pretty sure, it would be welcomed with open arms, and a catch up path would be offered to try to recover what was lost along the way. A sort of "Marshall plan" only that this time it would be to put the US back on their feet.
I hope the US dont keep going through this path that only leads to self-destruction..
