Look at the bright side, just 10-20 years ago it was basically just the SF Bay Area with tiny outposts in Seattle, Boston and Austin. Now all three of those are a lot bigger. NYC now has a solid tech scene. Boulder has one. Toronto is starting to develop one. Many secondary cities are starting to develop their own like in Durham, NC. Pittsburg is now on the map when previously all CM alums would leave the area after graduation. Even Detroit is developing a small scene.

Tech opportunities are still going to cities, especially those with the biggest companies, but it's spreading to more and more cities and tech companies now know they need to expand to other markets to reach new talent.
