No LANs? No way. (Score 1)

I personally don't believe it. There will always be some kind of "LAN", even if everything is interconnected. Especially the longer we use IP4--there simply aren't enough IP addresses for all the devices. Internal IPs must be used. But even if we think simpler then that--a WAN is made up of multiple LANs. Each building must have its own LAN or wireless access point to interface with the WAN. There are tons of other reasons that simply having one big WAN (like every device having its own IP), like network security. Gosh, even having your network printer freely accessible on the internet. You can't just block that out easily... I remember the days back in middle school where every PC in the school had its own static IP live on the internet. How times have changed!
