I made a quick search on Google and Amsterdam turns out to be less expensive than the cities you cited.

Every time I read one of these "the Valley is moving to X" articles, I'm reminded of the last 15 years of "the Valley is moving to X" articles that haven't come true. Tech is a huge industry, and growth allows for jobs everywhere. I don't know why all of these articles have to be phrased as if jobs need to leave the Valley to make it happen.
About the "the Valley is moving to X" I can tell you our objective is not to move the Valley here. What we want to really accomplish is to build the some sort of evolution of it. We want to build a great community and make Amsterdam the technology and innovation center in Europe. The outcome looks bright and we are very optimistic about it.
We definitely do not need to move the Valley here for Appsterdam to be successful, Europe is full of great talent. But of course people from the Valley are welcome as well and can make our community richer.
And yet the subject of the OP is: "Say hello to Appsterdam: developers aim to move the Valley to Amsterdam"
Of course, if it was a less clickworthy title like "Amsterdam trying to increase number of tech jobs", we wouldn't have seen it upvoted.
