thinking about how it seems like there's a lot of stuff on youtube etc trying to explain big O notation to people (which youtube keeps recommending to us for some reason), when it feels like such a simple and basic concept to us, probably because we already understand it fine

@socks yeah it's something we work to avoid, i'm just wondering if it's a thing that happens for everyone or if we're unusual in that respect

@Felthry It is common. You see it a lot when people without consideration tell someone else who's learning "come on, this is easy!"
@Felthry It is a very common problem to have, and part of what makes good teachers good is learning to see like someone who doesn't know, and what tools can help someone learn.
With Big O Notation, specifically ... there's some topics pop-mathematics really likes. I think it's things in the sweet spot of being stuff lay folk don't know but could understand without too much work. See also the different sizes of infinity and 0.9999(repeating). So they get explained a *lot*.
@Felthry It is a fairly common brain glitch. Not your fault, but also something to put conscious effort into avoiding. Assuming that someone must know something can make them feel bad if they don't
