I lived in Austin from 1999 until 2023. The irony here is that the main reason the city is soulless is because of the steady influx of douchebags like themselves.
In the 90's Austin was arguably the slacker capital of America. The dot-com bubble killed that but after the bubble burst the tech folk that stayed behind decided to do their own thing. The Austin tech sector had a distinctly relaxed vibe. It felt sustainable and it felt like everyone knew each other. Big city tech center with a small town vibe. The downside was that we didn't have much on the way of amenities. Prices were low and a concerted effort was made to revitalize downtown. Soon we had good food, great bars, low rent, and a genuinely fun city to be in. Then the douchebags caught wind of it, prices skyrocketed, and they ran out everything that made the place a joy to be in.
Austin can still be great, but it will never be L.A., and thank god for that.
