For example, we now introduce E. Coli DNA along with mouse DNA to hog embryos strictly to reduce the hog's phosphorus output, making them much more environmentally friendly. We introduce scorpion venom DNA into cabbage, to produce cabbage that has a natural resistance to pests. These are only a few examples.
Yeah, except for the powerful "may allow your descendants to live much, much longer" claim, no specific claim was made.
And yes, I am aware that those have been done. Unfortunately, we are more complex than a plant, e coli, etc. despite similar regions of our genome. Gene therapy for us has been inching toward progressive treatments, and has been met with some disappointing obstacles in humans.
We can't even begin to fathom the claim you made at this point in gene therapy research.
