I realize this is off-topic, but I'm somewhat surprised by the consistent use of the Austin metro as an example of a "tech hub" in comments here, when a metro area in its own state (Dallas) had raised more in venture capital as recently as 2016. [1] Austin is certainly shifting their economy to be tech-dominant, but it's still a small economy relative to other US cities.

What makes Austin a more important tech hub than, say: Dallas-Fort Worth, Raleigh-Durham, or Chicago?
