I think that this is the most likely scenario, at least for the developed world, but I don't think that it will take 25 years and I don't think necessarily that people have to be hurt in the transition. If people are hurt it will likely be because of the traditionalists and Luddites who are resistant to change. The people who are standing between us and a more fair and equitable future are the same people who stop us from having a more fair and equitable present.
