Can’t play disc based PS3 games on PS4 either. What’s your pointThat's if BC is there. If BC isn't or if its incremental, you may not be able to play certain titles again in the future. Imagine the dismay to all the PS3 owners who bought loads of content off of PSN that can't play them on PS4(PS1 classics, PS2 classics and PS3 games.)

It’s also been stated that this holds true with digital games as well.It has been repeated in this thread dozens of times but to reiterate, whether a console goes obsolete or not doesn't change the fact that the physical disc will ALWAYS be playable on that console.
PT is a shytty example. It’s a damn demoAny game I ever bought on PS4 physically will always work on PS4 regardless of any conditions people lay out such as "Oh but the game has a huge day 1 patch!" or "you have to download the rest of the game! or "You still have to install it so !!!"
Yeah, that last excuse? It's an OPTION still whereas if it was something like say PT where it's not even downloadable anymore, it CAN'T be reinstalled since it would require a download first.

Otherwise any digital game you’ve ever purchased on PS4 will always be playable on your PS4.
Discs are going away, don’t matter how any of you feelI'm not against digital games, I own a lot on PC but the landscape on PC is far different for reasons mentioned already. I can buy games from many different storefronts at big discounts relatively early and Steam started as a digital store front so there's no physical disc expectation with PC games.
In the long run this issue may not affect everyone and there's pros and cons for both sides so personally I'd like if both options existed. I see no reason for physical discs to go completely away. I see no reason why things have to be extreme on either side. A mix of digital games and physical is fine.
