When most people think of this, they think: “Oh, DNA editing will make our life sooo much easier! I can grow muscles without working out!” First off, that’s not how DNA editing works. You can’t grow muscles by changing your DNA. However, DNA editing brings many more scary things. For one, when you have your DNA edited, you are placing your lives in the hands of the operator.
Sure, this is true with surgery, but with DNA editing, you are taking it to a whole other level. One nano-meter of error could kill you. Furthermore, scientist aren’t 100%, or even 90% sure of what each DNA strand does. Like code, if you change one strand (or code), your entire DNA could fail. And there is no undo or CTRL + Z.
