What is the USP of the countless others? They even converged on API.

Being in EU is actually a rather strong USP with history happening. Just the other day Korean workers building a factory in US were detained and publicly humiliated and sent back. At some point there will be an incident where ICE/TSA or military deployed to as a police will kill a family member(a mother that doesn't speak English, a father that looks islamic etc.) of prominent researcher or entrepreneur and the compensations will need to go even higher to convince that it’s worth the risk(like the people who work at refineries in warzones). Most of the AI researchers and developers are foreigners, some very prominent of them are Europeans and when the risk with Trump is realized it will be very important having place for them to return and this is a huge upside.
