Wow, I'm drinking tea as I read this! (don't have any scones, alas)
I don't think we will become more civilized at all, in general, until something about our lives changes, and my conceit is that we need to live longer to achieve that.
I have a LOT of things left to do, and one is being around when we finally, officially meet aliens.
One of the others is to create a model city, with a new approach to society, sustainability, and the future.
Way too much to get to in the next decade or two, and yeah, no diapers for me.
