I agree. My PhD is technically in CS but it made heavy use of algebraic topology. Being 5 years out, having worked briefly in tech, then at a national lab as a software engineer has given me enough outsiders' perspective on pure math. You probably need to work as a professional mathematician to be at the research frontier of a given area, but otherwise the fundamentals of math are unchanging, and in my opinion, that makes it accessible to anyone who is sufficiently interested in and passionate about math.
100% agree with this. I used ChatGPT earlier today to give me networkx code for computing the connected components of a graph and visualizing the graph. This isn't hard to do, but I don't use networkx all that often and I forget the exact API. I could go to read documentation and piece together an example myself, or I could ask ChatGPT for an example, which tends to be much faster than doing the former.
