Great way to store information, such as technical specs/blueprints, etc…. in RNA/DNA! Just eat a few select items, and download it into your bloodstream! Great for espionage. Of course, the specifics are something I can’t get into here. I would also use this to track vaccinations and the medical history of humans in developing countries, from infancy. Or perhaps with a transmitter ‘chip’. Of course, all of this could blow up in my face, so I’d have to be very careful.
