you could teach someone the notion
of playing that riff quickly, yes... could they get it up to speed, played properly, and sounding good without a pretty large base of skill? No.
I generally don't like to tell people they're just wrong but... you are wrong. In fact I would almost guarantee that if you're the sort of person who thinks that this is easy, you're playing it either badly or incorrectly.
Either way, there's a lot going on, even in just that opening riff: picking at ~210 bpm (even if you're not downpicking it like you should), quick release of the palm mute (especially during the last run down), quick position shifts throughout... and that's just that riff, which is the simplest riff in the whole song.
Like I said, I reckon you're playing it badly or incorrectly, and if you're not then you're so far away from being able to teach anyone else because you've lost all sense of objectivity on what is difficult and what isn't. All you're going to do now is discourage people who can't do this yet. Your whole mentality is going to have people saying "Well this is easy and I can't do it yet, maybe I'm just going to be awful forever then?". You might not mean to but everything about this attitude is going to harm beginners.
I would also suggest that next time you're going to start a sentence with "I'm not trying to humble-brag or anything, but
", you might want to have a look at why you're saying it. I suspect it might just be that you are, in fact, just trying to make yourself look good. Problem with doing that here is: we don't care
Please, reexamine what makes something difficult, and reexamine your attitude.
