Most new hams aren't doing CW but a surprising number are. It's become hip to learn CW now that it's not a bitter pill to be swallowed - now it is an interesting choice and an inexpensive way to prove one's self in the eyes of the Old Guard.
That said, my point was there's plenty of CW activity on the bands. I don't know about 100 years from now but right now it's doing fine.
A friend out west very recently went from walk-in to General, doesn't even have an HF rig yet, and first thing he asked was for me to burn some CW course material on a DVD for him. Thought that was pretty cool.
