Yes! I've found that public speaking has become almost second nature to me over the years only after becoming an absolute expert in my field to the point I generate unique research and can bring new things to the table. As a result, I may prepare a slide deck ahead of time and am usually still working on it just before I speak. The slide-deck itself are breadcrumbs. It's there to keep me on subject but in terms of preparation, I don't prepare because I don't need to thanks to how well I know the subject matter.
