I think as awful this sounds, it is also why often adhd people can synthesize a lot of information very quickly because their brains have this rapid association chain which can lead to absolutely lucid insights, downside is that it's hard for them to stay on topic and not go into rambling monologue mode.
I always had that. I can’t go as deep on subjects without force of will, hard. But I have always had a knack for integrating information and learning new things with a relatively high amount of new things but not a lot of density for each thing. This can add up, sneakily, to very dense knowledge on a subject and I have made that a part of how I learn. It’s great learning new frameworks, languages, and subjects. That surface scan and seeing the whole of something comes easily.
