Nah, I think it's a fair assessment - I do a fair bit of concurrency work, and do a bunch of education stuff at work. I've built and helped fix multiple things close to or (regrettably) more complicated. It's not surprising that I guessed the general shape correctly. But there are quite a lot of people stuck somewhere between "can reliably use a single blocking queue correctly / coarsely protect things with one mutex" and "can handle multiple competing interactions with error handling". More material to help cross that threshold is definitely a good thing.
