Amazon will have to recruit young talent and must consider where such talent wants to live.
The Hill Country is an awesome place to live. These youngsters will have a commute, but infrastructure will eventually catch up.
Fredericksburg is my kind of town. Lots of quaint shops to occupy my wife while I sample the wares at 3-4 wine bars. The Museum of the Pacific War is a must see, too...before or after the wine bars.
