On reading the Weekend FT last Saturday, I stumbled on a piece entitled ‘Algorithm for our times’ about a man I’d never heard of. It’s the American in the photo, taken in 2011, who looks like a grizzled and possibly grumpy old man (says this grumpy old bag). It’s no wonder I, and no doubt many others, are unfamiliar with his name and face as he shunned publicity. In a rare 2006 interview he says, quoting Orwell’s donkey in ‘Animal Farm’: ‘’God gave me a tail to keep off the flies. But I’d rather have had no tail and no flies’’.
