DNA has another big advantage over any other storage medium: It’s future-proof. Do you have any old floppy disks laying around? Cassette tapes of music, or vinyl records? All of those are impossible to play unless you have the original machine to do it. These appliances may be available now, but who knows how easy it will be to find them in another few decades (or centuries)? DNA, on the other hand, “has been around for 3 billion years,” Erlich said, “and humanity is unlikely to lose its ability to read these molecules.” Erlich and his research partner Dina Zielinski estimate that commercial DNA data storage won’t be available for over a decade. When it is, though, the storage race may be over—and, in the future, data smuggling inside your own body will be a very real and creepy possibility.
