Synthetic biology will transform our understanding of family ties, our aging timeline, what we treat diseases with, where we live, and what we eat. In this rapidly developing field—using computers to correct and alter genetic code—revolutionary solutions have already been developed: from mRNA vaccines and diagnosis of congenital diseases in embryos to lab-grown meat that tastes almost indistinguishably from the real thing. It gives us a chance to address global threats—climate change, food shortages, and the energy crisis. But it also brings serious risks. Is it acceptable to release genetically modified organisms into the wild? Should there be limits on improving the human body? What cyber-biology dangers could we face? Could a future war using specially designed bacteria and viruses lead to mass extinction? Amy Webb and Andrew Hessel compellingly describe the present and future of synthetic biology, prompting us to think about the moral dilemmas connected with the purposeful design of life and the enormous prospects it opens before us.
