Wikipedia protects the past without impeding the future. That’s the genius of the View History tab, which allows anyone to browse and compare every single version of an entry going back to 2001. Of course, multiple versions of the physical world cannot be physically preserved. But if all World Heritage sites were virtualized like Wikipedia, the physical places could continue to change with the people. The mud huts of Djennécould be preserved as three-dimensional models, augmented with historical and cultural information contributed by both archaeologists and locals, wiki-style. Layers of alteration to the houses could be digitally recorded and accessed by anyone anywhere. Rapid prototyping technology means the huts could even be printed out and physically explored. Were world heritage wikified, people’s homes would no longer be reduced to graves, sacrificed to outmoded Unesco principles. Djenné would not become a moribund ghost-town-cum-tourist-attraction like Iwami Ginzan.
