I tend to think of nature in terms of "rpg sliders". You may not think you have autism, but you probably have a small percentage at the least. Everybodys got everything, it's all a spectrum.
Speedrunning is a weird thing. I like watching speedrun videos for difficult games from my childhood. Easy way to teach you how to finally beat that game. There is a corner you turn when you stop watching them though. You start to think "man, how can a person play only one game for thousands of hours this is odd". Ya it's a weird thing. I will say that it reveals that some people have amazing brains.
