Depends on the side effects, depends if you can safely and reliably reverse the decision.
Would I personally be patient zero? No, not likely. Will someone be patient zero? Yeah, of course, there's always people willing to be on a new frontier.
Can you safely and reliably reverse a find/replace on a program's source? Generally, unless you have a backup, the answer is no. There's also a lack of any kind of guarantee that the resulting program will compile, or if it does, that it will run without any more bugs than it had before.
CRISPR is just about the same way. We need to do research in ethical and humane ways, ways that balance the possible gains with the possible losses. We've already had an incident where human DNA was edited, and not particularly ethically or responsibly. I'd really wish that people not bring sci-fi futurist fantasy thinking to this particular table.
Bad analogy as source code is one of the things that is super easy to reliably reverse anything as it is always in version control.
