I probably wont make a lot of sense as Im just musing but given that there is nothing unusual, or wrong in fact, with the world or society or communities being designed around the usual social norms/habits/behaviours of the majority, you would expect, IF it is true that NT people make up the majority, that the systems and behaviours around us are formed by and form the 'design of the world'.
That said, some of the modern world in my view, very technologically advanced, isolated, remote, distant, automatic etc etc, is often designed by people who are more likely to be ND, therefore the very systems that we all now work with and are led by and control us to some degree are likely to have a huge part of them influenced by the way that someone on the spectrum thinks and sees the world.
There is also another anomaly which perhaps is that those who are NT are not the majority, in which case the world is not designed for NT vs ND, it just is a hotchpotch of systems and behaviours at any one time. This will be borne out in years to come in my view in that conditions like ND dont have a diagnosis criteria cast in stone, its changed over the years and wil change again. So the way the condition is seen is a socially perceived and designed thing in and of itself.
