I completed the book Programming Principles and Practice using C++ (which I HIGHLY recommend to any beginner interested in software engineering) about year ago with GPT4 as a companion. I read the book throughly and did all the exercises, only asking questions to GPT4 when I was stuck. This took me about 900-1000 hours total. Although I achieved my goal of learning C++ to a basic novice level, I acquired another skill unintentionally: the ability to break down tasks effectively to LLMs and prompt in a fashion that is extremely modular. I've been able to create complex apps and programs in a variety of programming languages even though I really only know C++. It has been an eye-opening experience. Of course it isn't perfect, but it is mind blowing and quite disturbing.
