I think you've made my point; corks are not going anywhere and neither are vinyl records.
Most wine sold is fairly cheap and forgettable, and most of that may well be screw-cap eventually, but there will always be a huge selection of finer wines that will choose to use corks, your comments on aging (very astute) notwithstanding.
Most music released today is streamed, yet the bulk of that is also released on vinyl because a certain percentage of the audience appreciates the quality.
Books vs. ebooks are another analogy to vinyl records, maybe a better one... e-readers could hardly be much better than they are now, yet books still seem to hold their place.
