30 years from now the problems of today will be unimportant compared to the problems of the moment.
Is anyone here thinking about the problems of 30 years ago?
I am thinking about problems from 30, 60, 140, and 240 years ago - and some much older than that. The important ones rarely go away. The marquis problems of the moment are almost always transient species of timeless problems that simply reappear in ways that appear novel only to the unread masses.
About the only really new societal problem on the horizon is what to do about intellectual property rights and genetics. But that's one that's been brewing for a few decades, and will take a few decades more to truly come to a head. By the time some of the more critical decisions will be settled, it will itself be one of the "old" problems.
