> It's a good article but I think you need to start explaining structured concurrency from the very core of it: why it exists in the first place.

I disagree. Not every single article or essay needs to start from kindergarten and walk us up through quantum theory. It's okay to set a minimum required background and write to that.

As a seasoned dev, every time I have to dive into a new language or framework, I'll often want to read about styles and best practices that the community is coalescing around. I promise there is no shortage at all of articles about Swift concurrency aimed at junior devs for whom their iOS app is the very first real programming project they've ever done.

I'm not saying that level of article/essay shouldn't exist. I'm just saying there's more than enough. I almost NEVER find articles that are targeting the "I'm a newbie to this language/framework, but not to programming" audience.
