While certainly Austin has its problems (traffic, heat in the summer, and allergies would be my top 3) I find Austin is handling high growth far better than California did.
We do have older, homeowner NIMBYs here, including my local neighborhood association. The difference between here and California is that the NIMBYs don't have as much power here. They fought an apartment complex in my neighborhood and lost--now hundreds of new people are able to live closer in to downtown.
The current fight over zoning is allowing "granny flats", or back yard buildings. It does look like the NIMBYs are going to lose on that one as well.
There are also a lot of older houses being torn down, developers splitting the lot, and building 2 houses on the lot. These older houses aren't historic; they're 1950's-1960's suburban sprawl. I did not see California allowing these types of development as easily in the 10 years I lived there.
Overall, Austin has a compelling mix of factors that keep people moving here. The weather is great 9 months out of the year, and if you're in tech, it's not uncommon to work from somewhere else in the summer, or take some time off.
You're actually able to raise a family here without insane waits or crazy prices for daycare.
The community overall is more laid-back than SF because you don't feel the need to work 90 hours a week just to be able to afford a 1BR apartment.
Plus, we have breakfast tacos. :)
I've traveled through most of the US at this point, and lived in several different areas, and still think Austin has one of the best communities of people I've ever seen...which is why I continue to live here and advocate for smart tech folks to move here.
