SO ENDS this two weekend venture into the theme of coevolution. Clearly, this story is far from over, and there is more to learn. It is interesting to imagine that man and machine may one day coevolve when Artificial Intelligence gains its inevitable autonomy, and when flesh and machine inevitably become more entwined. So far, the story of coevolution in biology has been limited to closely interacting species, such as the microbiome and the host, but this will expand one day to extraordinary realms.
