Mass scale demolition !! Top 5 AWESOME Building Demolitions

This seams like such a waste of good buildings, unless necessary as not structurally sound. Technologies are changing and with a wireless technology future we may not have as high of cost renovating these. It maybe, in the future, that power and wiring systems could be floor specific or run an outside chase up with power and Cat and fiber optic lines. Hopefully in the future, I envision, wireless hubs, switches, routers, and sensor inputs (phone, CCTV, HVAC, communications,..),with wireless CPUs on each floor with floor or multi floor specific power supplies. If we can cut the wiring and labor cost, as well as, cut energy cost we can save these. The real question is: How do we define progress ? What's our definition of historic value ? Think about the money that just went up in smoke, In years technology could have saved all this.
