I think technology is making the general populace stupider. Presidential debates are a litmus test for what politicians expect of the populace. A hundred years ago they sounded a lot different than how they sound now. Does your nihilism encompass this change as well?
My tone might have indicated otherwise, but I don't have a solution because I don't really see a problem along this axis. I don't really care about how stupid everyone is, as long as their material conditions are at a standard I consider good.
