Why should old things always die if there is a demand and they are working fine for intended purposes? Let there be a cottage industry selling a single new floppy disk to upgrade flight software for $999, beats buying a new airplane. If we lost ability to make previously commonplace objects in limited quantity when needed, that's not good for our economy, environment or preserving entire cultural legacy of our civilization. Resurgence of vinyl is a great example of what can be accomplished in consumer space. Making floppies available as long as expensive machine need these could do same for enterprise.
