There’s been a lot of futurism in the news this week, particularly focusing on cities. First, Forbes.com has an interesting piece on Ghost Cities of 2100. Most of the cities they predict will be abandoned appear to be for reasons related to global climate change. Regarding future cities and advertising, could we be witnessing it right now as Sao Paulo’s outdoor advertising ban takes effect?

Scientific American is also running a related piece this week, but this it goes a step further than Forbes and describes a future with no humans at all. Things are looking a little bleak in the popular vision of the future.
