I think the older buildings will stand up o.k. Its the newer buildings I have concern about.

Look at places in Europe that have buildings standing for over 500 years now.

We use to build things to last.
So the old skyscrapers like Empire State, etc I think will be fine.

The new stuff though has a build in shelf life almost. All these glass and steel towers with cheap materials just won't stand up as long.
