I read that the rate of world population growth is falling. This is regarded in some quarters as cause for alarm: Suppose population growth levels off, or worse, begins to fall. Economic growth would stagnate. Unemployment would rise, or, on the contrary, not enough goods could be produced. My view is that leveling off of population growth is essential to the long-term survival of our species. It would be best for population to trend down to levels where despoilation of the environment is reversed. Why not free people for better and more creative living and let robots do the work?
