That comparison really isn't fair at all. Video games are made with wildly different code, different game systems in mind, etc..with music and movies, they can look and play different, but how they work is universal. You can watch The Dark Knight on an old tv but you can't play Super Mario Sunshine on an nes. You'll be able to pirate a movie until the end of time, but a game inevitably will eventually become unplayable if it's not physically preserved.
Games will change and improve but they'll never, ever be as simple and easy as downloading an Mp3 file or whatever. It just doesn't work that way.And the extremely negative impact on the gaming industry, the longeitivity of games, and how it screws over consumers in the long term, do not apply to movies and music, hence why people don't complain about those going digital as much. Like, call me a skeptist, but there's not going to be a day in our lifetime where we can buy the entire game of Skyrim for five bucks and jump right into it
The fact is, though-no such thing has happened. Just consider the fact that gaming PCs capable of running any current 60$ games are considered a niche and are (and will remain) much more expensive than any sort of console. And if you're going to go out of your way to head to the store to buy a console, what would you get? A 60$ eshop card, or the game you want, sitting right there on the shelf? Physical games are more likely to end up in someone's hands than digital games, and the more advanced games become, the more that fact remains true.
Cheap ass game companies want this so they can have pretty much no respect for their consumers. Don't let that happen.
