A wisdom deficit - fewer elders and even fewer people who listen to them.

When things get bad enough, then something happens to correct the course. And it's for that reason that I speak about evolution as an error-making and an error-correcting process. And if we can be ever so much better - ever so much slightly better - at error correcting than at error making, then we'll make it.

I think of evolution as an error-making and error-correcting process, and we are constantly learning from experience.
