True, I've read stories where researchers have done analysis of the DNA after the use of CRISPR and found that parts other than the target had been affected.

But like all decisions, you weigh the good vs the bad and you make a decision. In many cases it will be the best choice by far. Additionally, the more we use it the more we will understand the down side and we can plan for it.

Yup, it has a down side but we'll be able to balance the good and bad parts. Techies love to focus on the good of technology but I think it's good to point out the bad as loud as possible so we can plan for it. The fact is that the genie is out of the bottle and it won't go back in. So CRISP is part of our future.
