I have been to the Silicon Valley and it is not like Austin. How long did you live in Austin again? Perhaps the airports are similar.
I live near Austin, and my wife is from Silicon Valley. The two are no more similar than Silicon Valley is similar to New Delhi. Even the airports are very different. SFO approaches are mostly over water, AUS’s are all over dry land. The only thing similar is the traffic - both are like New Delhi. Austin is proudly weird, Silicon Valley is just nuts.
