I'm sure I am not alone in not being interested in relocating (even temporarily) to the US, at least under current conditions.
So... are there enough of us EU founders with global ambitions and SF-level work ethic to actually make the mountain come to us instead? What would it take for us to convince YC to make even one experimental but proper batch happen in Europe? (with global mentors and global VCs for a demo day etc.)
If there is enough interest - let's petition YC folks to make it happen, shall we?
