To be honest, everyone who wants to make one global system scares the hell out of me. Especially if it's mixed with some algorithms will decide what's the best for you mumbo-jumbo. Go ahead and build your futuristic city, but I will opt-out from living there, sorry dude.
You live in a current global system already, made by people a long time ago. At the moment we have a good technological progress, so why not to try to do something new and discover new things by gettting out from old system to a newer one?
