Plus, I always knew that PS1-PS2-PS3 BC was a pipe dream, i'm not annoyed that I didn't get what I wanted, moreso it's towards Sony's stance on it that it's not even worth looking into and that nobody cares about it.

What specifically gave you the impression that they didn't even look into it?
They don't report everything they look into to us. What they said was that AMD designed the custom chips with PS4 logic in mind. Can we agree that this by itself is already asking more of AMD than is normally reasonable to focus on?
To quote Cerny: "Achieving this unification of functionality took years of effort by AMD."
My point is that if PS1 - PS3 compatibility were to occur in the future, it's more reasonable to assume that this would be achieved by Sony purely (not AMD), figuring out an emulation solution. And this is still, in theory perhaps possible. But not something they should necessarily waste valuable time and resources from AMD to work on at the development stage of the console. And that's what they were talking about in the presentation. That they have PS4 backwards compatibility logic in place thanks to AMD. And even then, they still need to test every single game before before they can all function properly though. (So that's a lot of work to do just with PS4. Let alone with potentially PS3, PS2 and PS1.)
Microsoft have already found a successful way to emulate their older games since a few years ago, which gives them a head start on that front this time around.
If PS3 games can be successfully emulated even with PS5 remains to be seen due to the notoriously strange architecture of that system. But that's probably something they'd want to focus more on after the console is finalized and launched, as there are a lot more important things to handle in the meantime.

With the 3D audio chip basically funcioning as SPE per Cerny talk they may discover a way to emulate the PS3 with that who knows... but I would bet more on abstraction and generic emulator running on PS5 if they decide that remasters aren't bringing as much money same for PSNow (so I don't expect they to do it).
