I think maybe he just comes off that way because of how he presents things in videos.
Perhaps ironically, over the years I’ve found it’s those who cannot look past the tech-jargon to be the lesser experienced because they learn the words without fully understanding the concepts.
it can also be the case that the 'laymen explanation' is actually patently wrong -- not just over-simplified or 'dumbed-down'; wrong.
some things just require a certain level of background knowledge; this is why generally any 'celebrity scientist' explanation of anything with the word 'quantum' in the subject line is generally just down-right wrong.
there is no decent metaphor by which to onboard a laymen in certain technical topics.
that isn't to say that the 'wrong' answers don't have value in educating the laymen, but the liberties that some experts take in 'wrongness allowance' is quite different from one another.
personally I think it's the responsibility of the explainer to step aside at some point and say : "Look, this is wrong, but without the background this is as close as I can get you to understanding this thing, so just don't take what I say as gospel from this point forward." -- the reason this is important is simply due to the fact that the laymen doesn't stand a chance at finding out which parts are wishy-washy by themselves without some further guidance.
not mentioning where the fairy tale begins is what leads people into thinking that there is actually an alive/dead cat out there somewhere. they grasp the metaphor itself rather than the statistics concept that is being explored.
The point of videos like the aforementioned isn’t to give people a background into game development. It’s to give people who have no experience an overview for entertainment purposes.
The issue here is that many youtubers have sold factual correctness for a view count.
It’s such a common behavioural tendency with general audience publications that someone coined a law for it (the name of which I forget but I’m sure someone else on here can reply with it).
