No, normal selection is not out the window then. You&#x27;ve only added a second selection mechanism (parents) on top of nature&#x27;s. And I&#x27;m afraid that selection will be based on hype alone.<p>As to &quot;first impressions&quot; and such, they&#x27;re based on thousands of years of both social and genetic selection, and I don&#x27;t think those traits are conveniently located in a single location. Even then, what if the same genome location controls both &quot;first-look judgements&quot; and &quot;jump away from the path of that speeding bike&quot;?<p>As to editing the genome, I&#x27;m afraid I don&#x27;t share your optimism. I consider our genome to be a 3.2 billion-line BASIC program (the old-skool one, with line numbers and no variable scoping), without unit tests or documentation of course. Sure, you can replace a single line and still have the program compile or run correctly. But how are you going to conclusively prove that your modification has no unintended side-effects, for either current or future generations?
