A major factor in European academics moving to the US is that top US institutes can charge a small fortune, and some of that gets reflected in academic salaries. Interesting move by the US government to try to put them off... The wider availability of capital is a bigger deal though. "Attention is all you need" is available to people on other continents to read, but a computer scientist in Europe that understood exactly how big transformers were going to be and why had less chance of funding than a webdev in California with a pitchdeck full of cliches and me-too GPT wrapper for an industry they'd barely touched does today.
