Example Citation:
Robotics is hardly the only emergent industry that can expect the embrace of the techno-enthusiast. Maybe bathtub biotech will be next to capture the mindshare of the techie tinkerers. Maybe bioinformatics and the diffusion of genetic engineering technologies and techniques will inspire a new generation of bio-hackers. Certainly the technologies are there for those inclined to genetically edit their plants or pets. Maybe a mouse or E. coli genome becomes the next operating system for hobbyists to profitably twiddle. Perhaps this decade will bring a Linus Torvalds or Bill Gates of bio-hackerdom—a hobbyist-turned-entrepreneur who can simultaneously innovate and market his or her DNA-driven ideas.
