I've noticed this phenomenon as well - all knowledge that has ever been documented is considered common knowledge these days, but, most people don't have a working understanding of it.

It's sort of like the dirty little secret of the 21st century - knowledge is power - therefore you must know everything to be powerful - therefore, by faking advanced level knowledge of all things is the shortest route to becoming all-powerful.

So, we have all of these people who get upset by beginners because they're the weakest, least powerful people - even if we're only powerful because we've lied about the things we have a working knowledge about (e.g. quantum physics, how vaccines work, the pros and cons of wearing a skin-tight latex bodysuit vs. a t-shirt and jeans while riding your bicycle to the grocery store to get milk because it makes you 5% faster).
