Looks like it is using processing to do the animation.
I think that we need't use processing for animation. In fact, Geogebra is easy to accomplish them.
Just like after the invention of computers, those methods of how to do manual calculations faster can be eliminated from teaching tasks. Education shifted towards teaching students how to use computational tools effectively. This allowed students to solve more complex problems and work on higher-level concepts that manual calculations couldn't easily address.
In the era of AI, what teachers need to think about is not to punitively prohibit students from using AI, but to adjust the teaching content to better help students master related subjects faster and better through AI.
