What hope is there for artificial intelligence, when the real human mind plays tricks with our processing of images?

I am walking down a quiet London street this week, I spot on the opposing sidewalk a familiar tall, greying, slightly overweight face with ruddy cheeks. The sort of individual regularly to be found lunching in or around London’s Leadenhall Market in the nineties. We make eye contact, he smiles, and I turn and crossover the street saying, “Hello John, how are you?” He warmly greets me in a jovial British manner, mutters about it has been a while since we last saw each other, then apologises, “sorry, I cannot place where it was”. He pulls out a business card, exchanges pleasantries and asks the same. I glance at the name on the card, the brains goes into a deep search and I suddenly realise that the “John” in front of me is not, who I thought it was! It is stranger “John”, someone in residential property. I chicken out with, “I am sorry I don’t have a card with me, let me drop you an email with my details.” We bid farewell, me chuckling to myself about my cluelessness, and reminding myself that relying on instinct alone is not an exact science!
