The intelligence and the complexity of humans remained almost constant over the years. What is exponentially evolving is the complexity and the intelligence of our tools. And if not now then soon our tools will have intelligence, will be able to learn, to take decisions, to improve and to reproduce itself. And that means… life! And by the rate we and our tools are evolving soon we will be overcome by a more intelligent and complex form of life created by us for us.
Let there be life! :-)
