Hey, he is right. He reason why so many places are dependent on US tech is simply because it's there and it works. Remove that and those places will suddenly innovate to what they had and more.
Trump and his people thought it would cripple China to isolate them, and that Europe would just accept their position as a vassal of a belligerent state. Look at what's happening now: China is making their own chips, poaching talent and also has their own humungous pool of talent that is now dedicated to developing alternatives instead of building on US tech. Europe is discovering opensource now. Africa and Asia are seeing China as more valuable trade partner and buying a lot more renewable energy and building their own industries free of US tech.
Pulling out of a market to focus on "MAGA" and America First" was strategic mistake, but we should all be glad they made it. The more competition, the better. If Europe also starts producing chips and Africa learns starts building processing their natural resources to multiply value, instead of selling it, consumers and businesses will have many choices. The US might face actual competition on every front.

Yeah, it's very unfortunate, but I still have hope that things will get better. Even though the African Union is a mess, there's lots of good stuff happening despite all the meddling from foreign nations. Africa is a region in hard-mode because of all the resources they have that everyone wants. It is my firm belief that it won't continue forever. With better education and diaspora returning, things are changing.
