Crispr is just messing with a single beings dna. This is read write where anything can be stored. I’m assuming they have a specific language cuz tgac is different than 1 and 0. So you could have all of humanity’s published information on some amount of dna and it’ll only take up like a thimble. AFAIK, crispr is just like adding in a gene or deleting a gene. It’s not even writing for a person to grow wings or something. Much more basic.
