Silicon Valley has a much smaller population and land area than Los Angeles, but beautiful crystalline technological megastructures rise far above the surrounding landscape. Some of the most advanced AIs built by humanity run their environmental and security systems. Cars fly through a city that never sleeps on crisscrossing skyways reaching from the heights of the building tops all the way down to their ground level roots in a never-ending rush hour. It is a city of invention that celebrates the accomplishments of the human mind. It is an amazing place to visit.
