I am not asking for utopia. In fact, a world where everything worked perfectly, with no side effects, is its own kind of hell. I am a protopian. I believe in progress, an incremental betterment with corresponding downsides each year, inching toward a world that is desirable despite its many flaws. A protopian future would generate plenty of unexpected ills and unjust distributions, but overall the greater net benefits would draw us to it.
