I can tell you how it will go. "All these people have irrevocably destroyed [my] Austin. Costs are up, too many people, what I liked about it isn't the way it is anymore."
People have been saying that since I left Austin 5 years ago after living there for 15 years (as a San Antonio native).
"Don't Dallas my Austin" (and its sibling from the 80's "Don't build and they wont come") is the kind of mentality that put Austin exactly where it is wrt affordability and infrastructure
10 years sounds about right. Been that way for decades too. I remember people in the early 90's complaining how Austin had changed since the 70's. It's the one constant to that town.
