And those changes wouldn't be passed on to the next generation, right? Depending on how the change was made.
From my limited understanding of the mechanics behind this, we could (in theory)introduce changes in fully developed adults that allow them to neuro-adapt better than baseline, without passing those changes on down the germ line.
It certainly adds a new dimension to the designer baby debate. Why alter your child when they are a few cells in a petri dish, when they could choose certain modifications as an adult of their own free will?
