There is a blurry line between "new use case" and "more of the same old", I believe. In transportation for example : cheaper fuel makes it easy to import exotic fruits from far away (avocado?). It is arguably a new use case : we did not eat those fruits before. On the other hand it does somewhat replace some local food (assuming we ingest the same amount of calories). I did sometimes turn normal incandescent lights by day when I feel the light is too low. Now the threshold for "too low" seems to move slightly.
