Not totally sure I agree with everything there. After getting a PS4 I pretty quickly figured out how to mitigate these problems and make the process of getting to the game smoother:
1) The PS4 seems to download faster in rest mode. I can't 100% confirm it but that seems to be the case.
2) I initiate PSN downloads from the mobile app or a browser on a computer whenever I can, which is more often than I'm using the console. The interfaces of both are smoother than on the console. I basically don't ever visit the PlayStation Store from the console itself.
3) When I get a new disc, I just immediately slide it into the PS4 and let it sit there. I don't wait until I'm ready to play the game.
Every game needs to be The Witcher, guys.
Edit: I apologise. That was rude of me. I'm having a rough day.
Funny you'd say that. The Witcher 3 without any of the expansion packs is only 20GB. Fallout 4's base game is also only about 20GB. Mankind Divided unpacked is 56GB on PC, but the download is 20.
The main thing I agree with Jim on is download sizes. I think developers need to take more care to compress their stuff, but most just seem to go right up to the size limit of whatever physical medium they're using on consoles, and on PC they're already going way beyond that. There are groups that release cracked PC games that have been further compressed so they don't take as long to download, sometimes they aren't even half the original size.
Bethesda talked about how modular its asset pipeline is -- how they break up their art assets into small pieces so they can combine them to create new ones instead of doing new art from scratch, which saves space data-wise. I get the feeling Witcher 3 did the same thing when I look at things like structures and NPCs.
