math channels which use sophisticated visuals are completely horrible for learning

>want to learn about calculus
>open one of these meme math videos
>music starts playing in the background
>watching some random shit happening on the screen
>guy is talking at the same time as the shit is moving around
>can't tell what I'm supposed to focus on


>watch video with a guy with a white board
>explains concept
>write notation on the board
>explains notation

This is the best example of mathtards lacking communication skills

yes I'm an INTJ if you must know
