Outside of tech - the history of Las Vegas is fascinating. It's a whole city built on nurturing industries that are illegal everywhere else. Many of the early casinos (1920s-ish) were also built by the Mafia with funding from the Mormon Church - there's one good example of capitalism allowing a group to reap the profits of sin without engaging in sin themselves. And of course, the modern Las Vegas Strip is actually built just outside of city limits because they didn't want to pay taxes to the city.
