An idea from astrophysicist Fred Hoyle (from his book “Man in the Universe”).
In the evolution of man, chemistry has gradually given way to ‘electronics’. Simple life forms are almost entirely ‘chemical’ in character and yet the majority of human body is dedicated to supplying what the brain needs to function.
Early ‘electronic’ systems are developed to find food – sonar or radar if you like – smell, taste, hearing etc.
Then we go on to develop hunting capacity – a guided missile analogy might be useful here – we developed tooth and claw to go along with the developing ‘electronics’.
Now we are at a point where tooth and claw are no longer needed – what we need is data processing and the power to learn and adapt.
Just a thought but I enjoyed it.
