I just want to point out that the sentence you replied to starts with an “if”. “If those genes’ role is to alter the way synapses develop in the fastest growth phase, changing them when you’re 30 won’t do anything” (emphasis mine).
You described this as “At first you confidently assert that changing genes in the brain won’t do anything to an adult”. The difference is important.
This is in no way a comment on the object level debate. I simply think Lesswrong is a place where hypotheticals are useful and that debates will be poorer if people cannot rely on the safety that saying “if A then B” will not be interpreted as just saying “B”.
