Looking at history, though, it seems like most (all?) significant social progress comes about because old people that bitterly cling their views and (most importantly) their power eventually die off, freeing room for the new.
We live in a world that isnt controlled by feudal powers owning a good portion of the population not because of wars, but because younger and less invested people forced those conflicts. The results of those conflicts are accepted because the people for whom the old way was normal die off. The new generations are able to make their own mistakes, get invested in the nest normal, and be replaced in turn.
Now I fear we will make anti-agathics before we develop a means to actually change without people dying.
I still hope. Someday we might live with death as a choice AND without oppression. Pretty sure I wont be around for it.
