SPHERE, LAS VEGAS

It will be all too easy for architects to dismiss the most expensive entertainment venue in Las Vegas history as the apotheosis of spectacle culture. But it seems unlikely that a critical vocabulary developed for quaint twentieth-century technologies like the cinema and broadcast television will prove adequate to understanding a $2.3 billion augmented-reality machine that has absorbed more resources than most major urban development projects, and anything that can gather tens of thousands of people into the same physical location at the same time to engage in the same collective activity is surely worthy of consideration by both cultural institutions and the architects who build them.
