Given the standard practice in lab experimentation using mice (which is to "dispose" of them after their usefulness for a test is done) I'm extremely troubled by the idea of gene editing experimentation using mice to make them more intelligent (their standard intelligence would already be surprising to many people).

While I already think it's unethical to use animals the way we do, the idea that we're experimenting with how close we can get to bestowing them with human intelligence before killing them is saddening.
