Agreed. Some gifted people create stunning works of art with unconventional or limited tools. Tatsuo Horiuchi uses Excel to create beautiful paintings. I guess my point is that it's hard to argue against using non-destructive editing if it's available and you understand it. Can you create great things without it? Of course. Bringing the analogy back to programming: some people create useful/beautiful apps without using any form of revision control, and that's fine for them. But if you know how to use revision control and have access to it, then is there really any strong reason not to use it, especially if you're working professionally? It helps increase productivity far more than not using it. For that reason, I'd definitely tell other developers that if they aren't using revision control for professional work, they're doing it wrong. If you were to pick two professional photographers or retouchers at random - one who uses non-destructive editing and the other who doesn't, I'd be willing to bet the one who uses it (all else being equal) produces more consistent, high quality results and with greater efficiency than the one who doesn't.
