In what way are the tides turning? We've been reading news articles on how Berlin is Europe's silicon valley for the past 10+ years but I don't see much VC or interesting tech giants coming out of there, or high paying job there. The only thing they seem to have copied form SV is impossible to find housing for outsiders, though I think it's easier to move to SV than Berlin now.

Tides turning and motivation aren't enough. You need venture capital, and EU has none. At this point, every EU city that has some web dev body shops and one built a food delivery app then calls itself the SV of Europe to the point it's become a meme.

SV is more than overhyped VC funded apps though, you have Berkeley and Stanford next door, the biggest defense contractors outside, with all the gray-beards of 3D graphics there, all the gray-beards of silicone and RF there, of CPU design, of kernel development, etc. You can't replicate this highly experienced melting pot of CS and HW expertise anywhere else by throwing some VC money in a hippie city that has a technical university.
