OK sometimes I get really confused about the current state of education, whether I am too old already, or if I went to an extraordinary school when I was a kid and never knew, or what the fuck.

I am watching a 7 hour YT video about Linear Algebra just because that's how bored I am, and the presenter is going through the outline of the contents and how this is the fundamentals of data science, machine learning, AI and I guess the prevention of balding too.

So an intro about vectors, vector operations, Pythagoras, trig, angles, etc., then dot product, then on to matrices, Gaussian reduction, transposition and inversion of matrices... and she says how this is stuff that people encounter in 2nd or 3rd year... of university? What?

I am pretty sure I did this in middle school, or maybe it was high school already ("high school" started after 8th grade back then) but I know I did it.

Especially Gaussian reduction and matrix transposition and inversion, because yes, that shit is traumatizing when they make you solve it on the blackboard with the other 40 kids watching, so how could I forget.

The point is, I studied languages in uni, nothing even remotely mathematical in nature, so whenever all that was, it happened when I was a kid.

Are you seriously telling me *kids these days* do not learn any of that in middle school, or at least high school?
