I agree that not everyone has a knack for it. But I don’t think that’s the only factor. Software design/architecture is also hard and many devs aren‘t particularly good at it. We still recognize it as an important skill that requires education and training (and experience). If even just 20% or so of devs would get up to speed with how to write adequate documentation, and were enabled to invest the necessary time for it, that would already be a huge improvement.

Are you implying that a significant amount of coders are "on the spectrum"?

Not that I disagree -- working in highly technical fields this long, I could categorize 80% of my co-workers as lacking typical social and communication skills and you never know the real reason. It's to the point where I see women get promoted to management roles more often because they're superior communicators.

Everyone is on the spectrum. Coders are just closer to one side of it :)

I am strongly implying that, yes!

You can do surprisingly well in this line of work by simply not being an asshole.

Yeah, the social skills threshold is amazingly low...

I think that technical communication isn't the same as other communication, so I don't think it's a logical given that people "on the spectrum" would be bad at it. Technical communication is about conveying technical information, at various levels, with just a few constraints. It's a solved problem, really. It just needs to be followed to the letter.
