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.

True. But I think his point was that by not investing in other parts of the country, people are not giving a chance for the ecosystem to develop.

I think local culture plays a big part as well. In most other parts of the country people join big large companies and then spend their entire life being the company man or woman.

If I did that I'd cry just like the other guy said he would if the Bay Area got paved over.

If you have remote workers, you have a very very large ecosystem.
