I think 'the ecosystem' consists mostly of people with connections to money. Which of course is true, since the money is so provincial. Yes, there are lots of engineers there too, but as the article points out, they all have jobs plus back-up offers lined up three deep. Instead of going to the trouble to import people, why not invest in them where they're at? I'm not talking about farm towns in Iowa, I'm talking about places like Boston, New York, Austin, Atlanta, Chicago, etc, etc.
