And no, the world is not "designed" for anybody
The world as we experience it, due to the influence of our societies, is designed to benefit the wealthy, maximize their profit, and keep them in power. To that end, it's also designed to reward those who help them achieve their goals, and punish or indeed eliminate everyone else.
The world is an average of the people in it and being neurotypical is not a sin in any way, even if you try to make it one.
Speaking as the voice of privilege to tell us all how to fit in will surely help!
It's not a sin to be neurotypical, but GP never asserted otherwise. Neurotypical people do often act like it's a sin to not be one of them, though, as do many aneurotypical people who are lying to themselves about whether or not they are.
Society depends on both kinds of people, but as it was in fact willfully designed, it doesn't need many geniuses (who are generally atypical in multiple regards) and does need a lot of people who will show up for their wage slave jobs to crank out more bullshit widgets we don't need in such profuse quantity if we would build them to last instead of to maximize profit.
