When I was studying Mathematics I initially thought TDA was magic. I remember seeing MATLAB correctly compute the Homology groups of a Torus from a randomly sampled point cloud. As I veer farther into the CS/ML world I've come to appreciate that most of the advertised practical applications of higher Mathematics are quite niche. Having said that, Algebraic Topology is still one of my favorite areas of Mathematics from a purely mathematical viewpoint.
