This attitude seems unrelated to the topic at hand quite frankly. Experts suck at empathizing with learners not because of this spite, but often because it's actually quite difficult to switch gears in language and understanding. It's a completely different way of sharing knowledge, where you have to explicitly express things that are just assumed shared understanding among colleagues. Also, to answer your questions in a very simple way: the entire reason you even became an expert is because another expert somewhere along the way gave you an easy in to the knowledge, they coddled you. This is why you can "stare at a compiler error for a few hours before figuring out what's broken". Without that expert, you wouldn't even understand what a compiler even is.
