It covered some of the amazing projects scientist are working on using CRISPR, like bringing animals back from extinction and curing diseases.

One set of pictograms, one model; one gene, one disease; one snip, one cure.

I want to stress that the molecular scissors metaphor is pretty damn accurate as far as it goes.

This metaphor ignores an entire ecosystem of moving parts that are crucial for understanding the awe-inspiring, absolutely insane thing scientists are trying to do when they attempt gene editing.

To design experiments and interpret results effectively, I need a solid way to conceptualize what it can (and can’t) do.

More precisely, CRISPR is malware that can search for any chosen 20-character line of code and corrupt it.
