> Modifying the source code of humans is like the new hire thinking they can make the code so much faster because they don't know how the section code they are working on is used by the larger system as a whole. All they see is that there's an apparent bug in the section they are viewing now. Never mind the sections of code that have programmed workarounds for that specific bug, and will now break downstream because the buggy returns are no longer present. So how do we know if these kinds of workarounds in the human genome are also not present?

We know for a fact the current code base is full of bugs and convoluted workarounds due to the original coder having no idea what they were doing. While we may not yet know the best way to refactor the code, it undoubtedly needs to be refactored.
