(not the Mix thing and the data structure) In the age of AI... just kidding, this is no AI talk. This is a talk about humans. It's about things that have been told before, but that I got to experience myself throughout my career—and life, for that matter. It's the story of how knowledge dances around different fields, mixes up, and creates. It's advice for younger engineers about specialization and generalization, about impostor syndrome, and about trying to be successful. Beware: this is not technical in the software engineering sense. I promise to make up for it by citing as much research as I can!
