What about using them as guides to realizing you enjoy this work? Even if you don't understand all the details? What about if you come from a different field of research and are interested in the bigger ideas---even if you have the mathematical background? What about just wanting to know a little more than you did before?

This is a pedantic comment that isn't useful for anyone. I do research in an intersection of these fields (photonics, statistical learning, and optimization theory) and I often find myself expending a lot of effort reading a paper in a field that's just outside of that reach. Reading this isn't "trying to find a shortcut," yeah I can put in the work to understand Shor's algorithm[0] from the original paper, or I can read a post with the bigger ideas and then go through a formal proof on a textbook on the original if I'm actively interested, instead of spending 5-10 hours of my time reading through the paper, understanding the complete notation and then filling in all of the missing steps that appear in such texts just to find out that it's not that interesting to me, in general.

Posts like these are the reason I've learned about fields I didn't know about before---sometimes they've also been the reason I've realized some of my work has analogues in different fields than my own.

Don't just put other people down for the sake of doing it; if people read this and pretend they're experts on the topic, then, like being an 'armchair expert' in any other topic, it'll be evident from a single conversation with them. Apart from that: who gives a damn?
