I think I agree with you. I didn't mean to imply that big corps will build faster (or more) -- in fact I said I don't expect them to right now, and I'm not so sure that will change.
What I believe is that early prototype development and pivoting is insanely fast now. And if you find excellent engineers who are also great product people, and then pair them with people who have truly great ideas, many wonderful new products will emerge.
