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.

Somewhere there are records of every text message that someone sends and receives. It seems like it would be fairly trivial in the near future to use that to model an AI version of a person that you could continue to text with even after they are dead. The experience would be the same even though you would know that the AI wasn't real.
