As a European myself, I think it is fine to generalize* about Europe. Many points in Varsavsky's blog post were correct and it raised awareness of some things to consider. Sure, it had its omissions and errors, but also remember it was a blog post, not an article in a peer reviewed journal. Reading the article + the ensuing hacker news discussion one is already much better informed.

What is naive is to expect some blog post to give you an overarching view of a very complex subject. Kind of like reading a wikipedia article something and expecting to be expert on the subject matter after that.

*Making generalizations is a wonderful property of the human brain. Without that we'd all be lost in the fractal complexity of everyday detail.
