Over the [many] years John has become an advocate for “down to the metal” architecture. Today we seem to have forgotten how powerful the machines we are using are and settle for something that is typically only 10% of what can really be achieved. Abstraction and laziness leave us accepting what we have and that doesn’t scale. Today he spends a lot of time working on AI and the mathematics behind it. He’s a keen cyclist doing around 200km a week. He is married to a French wife and has 3 boys (21, 18 & 16) who all love travelling (as long as there’s internet).
