In Brainmaker Sukanto Bhattacharya examines the co-evolution of human and synthetic intelligence from a socio-anthropological perspective. He begins by presenting a history of technology discovery and adoption by human society, underpinning the uniqueness of synthetic intelligence. In subsequent chapters he critically comments on the challenging facets of human-AI co-evolution exacerbated by proliferating AI-labelled gadgets. Bhattacharya identifies indicators signalling that the human-AI co-evolutionary trajectory is about to, or has already, hit a turbulent patch with unknown and likely undesirable outcomes. He highlights the need for a new, more holistic ontological framework to cast intelligence, biological and artificial, as something more than a mere collation of cognitive capabilities. In the final chapter, he posits a few controversial conjectures on human-AI co-evolution.
