Yes - this is one of Gwern's big points. There shouldn't be any easy way to improve on what evolution tried to do, because evolution would have done it. But there can certainly be ways to optimize for things evolution didn't try to do, like preparing us to do symbolic logic for 40 hours a week or stay up well past dark. And there can be ways to optimize for goals evolution didn't/couldn't reward, like "never having kids and staying healthy until age 90". I do think there's risk in blurring the moral point with the practical one, though. I'm not particularly evolved for reading books, but it's something I enjoy and I want 'hacks' to do it better - whether that's reading glasses or a cup of coffee. I don't like commuting while tired or being stationary for hours on end, and if I had free choice I'd stop doing those things instead of hacking myself to be better at them. But in "enhancement" terms, they both count as "doing a thing I wasn't made to do" regardless of whether I want to keep doing them.
