The eventual ability to use a brain to reason about and change your own species's genes isn't evolutionarily selected for? The brain and human intelligence itself doesn't exist outside of evolution. If it turns out that humans being smart enough to modify their own genes doesn't work out, doesn't produce viable offspring, and ultimately loses out to undirected selection, would we say that that's a failing of our capabilities or that evolution didn't select for human control of their own gene selection? Does the answer to this question change over different time scales or if our evolution was to be studied by other intelligent species? It ceases to be undirected natural selection, but continues to be evolution. "Intelligent design" assumes an intelligence outside and other than humans. This is part of the "playing God" argument against research in this area. So while I agree that the term "intelligent design" may be more appropriate, that doesn't preclude it from still being "evolution" over the long term (which is largely what evolution is focused on). I'd also rather not have the terms get mixed up; calling this "intelligent design" serves to confuse the ongoing religion vs science argument/debate that is holding back innovation and laws in this area.
