I'm fascinated to see how philanthropic society will choose to be. Here's why. With the advent of robots I believe that something fundamental has changed. Elites, if they so choose, will not need to accommodate lower classes.
Previously, there had to be some sharing because elites still had to rely on other humans for policing and military. However, it seems like robots might cut that connection. What will happen when elites feel like they don't need a large part of the population? Will they be altruistic?
I don't know. Personally I'm pretty cynical and think we're heading for a future that's both more egalitarian and dystopian. The internet will give people a similar opportunity to succeed but those who do succeed won't be charitable to those who don't.
