I was born into a sternly Presbyterian culture. Politically, I’m more Orange than Donald Trump’s skin tone. But today I am on my knees giving thanks to the Pope. He has produced the most powerful political document of the year, taking on the greatest challenge of our times. His first encyclical, Magnifica Humanitas, deals with the changes which will be wrought to all our lives by artificial intelligence in the months and years ahead. AI will transform our economies and societies massively and irrevocably; it will change what it means to be human; it may even mark the end of humanity itself. If it takes the Pope to alert us to this revolution then perhaps the Reformation wasn’t such a good idea after all.
