Technological achievement
The tailored gut biota produces a significant reduction in obesity for 70% of patients. Leery of the self-replicating technology leaving their absolute control, it is engineered to require a chemical not found in nature. This chemical is patented and only available from the maker of the tailored gut biota. To nearly everyone's surprise, complications are minimal and the market value of the inventing company skyrockets. Global obesity soon peaks and begins to decline.
