Except we don't know exactly how these things work yet. It's not like CRISPR or even our understanding of the genome is very good. (Except a few mutations we know are very bad.)

So I can agree to a certain point, but it's not like we are at "sure, fire away" levels like in Star Trek.

I agree that as with any new and powerful tool, caution is required, and it is important to make sure that parents fully understand the risks and are not misled to believe that CRISPR is the only solution when it isn't. But i think it is important to remember that we do not use it because it is not ready yet, not because it is somehow inherently evil.
