It is one of those things as an outsider you think that something is overly complex, and then you learn it, and understand that it's complex because the issue it is tackling is dynamic which often requires a level of complexity to apply over. I had the same thought with Regex before learning it. Now I can read it like css selectors, and you'll notice that the complex patterns are that way because they have to cover dynamic situations (using ranges, lookbehind/lookahead, etc).
