Newmark's Door

From a Twitter account that is "A Compendium of [prize-winning physicist David Deutsch's] explanations". This post, arguing what we should do about global warming is, in my opinion, really excellent. A key excerpt:

Hence, we need a stance of problem fixing, not just problem avoidance. It's true that an ounce of prevention equals a pound of cure, but that's only if we know what to prevent. If you've been punched on the nose, then the science of medicine does not consist of teaching you how to avoid punches.

If medical science stopped seeking cures and concentrated on prevention only, then it would achieve very little of either.
