It’s not gloom and doom if it helps to frame the problem.

It’s not gloom and doom if it helps to frame the problem.

I know, I know — you don’t want to read another doom and gloom blog. But, in a recent article in the National Review* (link is no longer available), Peter Thiel does an excellent job of linking the desperate necessity of advancements in technology and science with the broader societal crises we are now experiencing. Thiel posits that there is a mistaken, but nearly universal, background assumption about easy progress that underlies our unwillingness to tackle difficult problems.

Optimism in a time of pessimism.

Optimism in a time of pessimism.

Back in 1974, Stewart Brand’s advice was to “stay hungry, stay foolish,” as a way of bringing a beginner’s mind to new challenges. He still follows that advice, and he now says, “The phrase allows you to open your mind and explore. It means putting aside the explanations provided by social constructs and ideologies.”
