I am not sure what exactly you wanted to say. All I got from reading it is: "human anatomy is complicated, non-biologists hugely underestimate this, modifying the anatomy of human brain would be incredibly difficult".
I am not what is the relation to the following part (which doesn't speak about modifying the anatomy of human brain):
It felt implied that 'rationality' was a culture of either hacking humanity, or patching together the best practices accumulated in the past
Are you suggesting that for increasing rationality, using "best practices" will be not enough, changes in anatomy of human brain will be required (and we underestimate how difficult it will be)? Or something else?
I am not sure what exactly you wanted to say.
I read Romashka as saying that the clean separation between the hardware and the software does not work for humans. Humans are wetware which is both.
