Where is architecture's Silicon Valley?

Or does it even exist? Seems like many industries have a cultural hotspot in the US. Hollywood, Wall Street, Silicon Valley, Pharma, Music City, Comedy, Napa Valley, DC, Hospitality, many industries have a place to be. Is it just New York City in general? Or are we just too diffused throughout the major cities in the country to have a true hotspot for design and architectural innovation?
