The fields of bioengineering and synthetic biology have already produced some useful, scary and flat-out bizarre entities. Besides renewable petroleum or steel strong spider silk, there are all sorts of potential therapeutic, industrial and agricultural purposes for reorganized DNA.

But DARPA thinks progress is too slow. Previous projects (it calls them “primitive”) are ad hoc and labor intensive, chugging along by trial and error in secretive silos. Hence we are “limited to producing only a small fraction of the vast number of possible chemicals, materials and living systems that would be enabled by the ability to truly engineer biology.”
