There are only a few factors driving this and they are very hard for Europe to solve:
- the Bay Area an industrial cluster not comparable to anything we had before due to the scalability and the capital requirements of the products
- the US market, the most powerful consumer market in history allowing massive economies of scale at companies, companies can work with a much higher productivity level
- capital markets that can finance the most outlandish ideas
- better demographics
- less crisis and russian intervention (Brexit, Syrian war, Ukraine war are all part of Russias attacks)
- bureacracy and regulations are totally overvalued as a factor, definitely something we should solve, but the EU would not be a tech leader without GDPR
