The difference between the “Austin sucks now compared to 10/20/30/40/50/60 years ago” is that there’s now actual evidence that it’s more true. Austin is no longer topping any of the “best places to live” lists. There are plenty of good arguments that Houston or San Antonio or Corpus are better places to live.
That said, there’s still plenty to love about Austin. We now have MLS to add to UT sports and F1 to add to SXSW. There are a shitload of great restaurants and breweries that have opened in the last 10 years. But instead of being defined by the University, state govt, and hippy/music culture, Austin is now clearly defined by economic/career opportunity. That’s where it stands out relative to other cities. That trait will always bring huge problems like traffic, crowds, a loss of culture, and expense.
I will likely never leave because we are committed to living close to extended family, and I don’t think I could ever go back to living in a small town, which limits me to SA, Houston, or Austin. If that weren’t the case, I’d probably move to San Diego or Charlotte.
