CRISPR technology is analogous to a smartphone, allowing for the recognition of different genes by loading software (guide RNA) onto it, unlike TALENs or zinc fingers which require building a different device (protein) for each function.

“with Talons or zinc fingers the the analogy would be you have to build a different device for each one of these functions so for each gen need a different phone for each different Hardware y yeah so for every Gene you're trying to Target you have to build a brand new protein to be able to Target that Gene and that is very cumbersome and and and not very effective process with crisper the promise is that crisper is like the smartphone you can load software onto it to recognize different genes and the software is the crisper RNA”
