Rarely have I encountered a more cooperative flock of birds. I suspect these pigeons, pictured here on the famous Old North Bridge, have grown accustomed to human presence. Still, it does not explain how they learned to pose in such a nice formation. Jeanine and I saw the movie “Her” last night and I am still thinking about it. It is the first non-malevolent depiction of artificial intelligence I am familiar with and left me wondering about a world where computers “evolve” beyond their creators.
