If you make a VLC clone from scratch but intended to be used for kiosks, the mixture of features and how it operates may be different, but the individual features have assuredly already been programmed elsewhere before. Which is basically my point. It still basically renders video on a screen, and maybe has options to play/pause/mute/etc. Most websites are CRUD apps with stuff that's been done literally a million times before.

Yes, some people do novel problem solving with software. But it's super rare in the grand scheme of the millions of people in the world who program.
