No, you're wrong about Metalab - there are plenty of people in the Metalab scene who would respond to your ideas if you were to make the effort to present them .. metalab is a hotbed of new-startup activity and some of the hackers there are really trying to make money, rather than just get it from their parents, as so many "smart kids in Vienna" do these days ..
What you might be interpreting as disinterest in the subject of startups is more like to be a disinterest in the means by which you are preaching to the converted .. sure you're not just getting a negative personal response and broadly generalizing it to avoid discomfort?
