My aphantasia mainly feels like a super power, that I process at the conceptual level rather than the visual level. I feel like it helps me focus on the important things and ignore the extraneous. It's strange to read it described as a 'deficit' and as something needing to be corrected.
I came to say the same. For the longest time I never realized that I was missing anything. Most of my dreams don't feature color unless its relevant to the story. This is the superpower, no distractions. It allows keeping a large amount of context of related things, even without physical form, abstract things, while working through them. It also explains why I discovered early on that I can't stand descriptive prose that paints with words for pages to set the scene before getting on with why any of it is relevant.
Although I don't feel like I'm missing out, I read that Nikola Tesla was able to work out how to construct the first A/C motor by constructing it in his mind's eye. That's pretty cool, I'd never have to draw any system diagram again except to transcribe for communication.
