is there any evidence or possibility that this is actually done in biology already? If DNA is writable, then cells have a Von Neumann architecture!

So, if I understand this correctly, it's like Johnny Mnemonic, but you don't have to store the data only in your brain. I bet if you used your entire skin instead of just your brain, you could store a whopping 500 gigabytes!

Joe Davis has been encoding data into DNA for some time.

I wonder what the equivalent of "rm -rf /" is in that environment? :)
