You must read the book "The Revolutionary Phenotype: The amazing story of how life begins and how it ends" by J.F. Gariepy, PhD.. It outlines how genetic modification will eventually result in DNA being replaced completely with a new system if we continue down this path.

Watch this short clip where he explains in detail what the book is about: https://youtu.be/mFQk7ausjd8?t=131

I do not mean to be advertising for him, I feel it's important for people to understand that what will happen will be equivalent to RNA based lifeforms being replaced with DNA based lifeforms...

Well, I strike more of a middle-ground. I don't personally expect to benefit from the technology. But I'm glad there are "early adopters" who will advance the science.

I figure, big picture -- The earth has had numerous great extinction events[1], if another happens, the ability to modify our genes may be the thing that keeps the race alive.
