That’s a great list. I would be shocked if you don’t get accepted to most of those schools besides Cornell, JHU, and CMU (although Wesleyan is tough too), and of course you might just get in one or two of those longer shots.
And yes, I think a graduate level degree is almost essential in this area of work. Undergrad work just lays the foundation for the real learning and research that is needed for essential innovations. It’s a long slog, but if you love the field it is totally worth it.
Best of luck, and if you think of it this winter and spring, let us know how it all turned out for you.
