A big problem that we have is that the internet is huge. It’s becoming so mind-bogglingly massive that the data centers we use to store parts of it in need their own power stations. Storing it on hard drives, in fact, would probably consume a couple of zettabyte’s worth of hard drive storage, and that’s already taking into account compressed data. We need a different storage medium to keep all this information on, and it turns out that DNA is the best solution that nature’s given us. Initiatives into using DNA to store digital information began about a decade ago, and recently we’ve crossed a milestone in storing, and reading back, data encoded in DNA.
And we did it first with cat pictures. That’s so meta!
