In Tokyo,the Sony HQ,also known as Sony City,sits at almost 100 meters tall.Built mostly out of glass and steel,how long can the building last?
1 day after people:The Tokyo power grid fails,and the building goes dark.
50 years after people:The diamond frame holding the glass is rusting.Finally,the floors collapse.Underground,the two basement floors career flooding.
100 years after people:The basement floors collapse,and the structure sinks into the ground.The glass shatters in a chain reaction.Then the frame collapses,bringing down the whole structure.
10,000 years after people:Tokyo is a forest.The site of the Sony HQ is unrecognizable.Sony is now extinct.
