The reason why PlayStation dropped backwards compatibility for PS4 was because they moved from the Cell architecture to a completely different architecture. The Cell is tough to emulate even to this day and would have been expensive to implement, and ultimately was found not to be worth it. The PS3 didn't exactly light the world on fire with sales records, and most of its best games are now available on PS4 and PS5, and PS5 is fully backwards compatible with PS4. Sony made a decision to get a fresh start in order to be able to price the PS4 competitively against the Xbox One.
Likewise, the PS3 originally included PS2 compatibility, but that was dropped because it was too expensive and Sony needed to cut costs. The PS3's original models included both the PS2 Emotion Engine CPU and the Graphics Synthesizer. So it basically had a complete PS2 in the PS3 casing. I had one of the original CECHA models. That was the only way to do backwards compatibility for PS2 on PS3, because the PS3 simply didn't have the power to brute-strength PS2 emulation. In the next round of revisions, they dropped the EE but kept the GS and maintained BC through partial software emulation. After that, they dropped the GS as well, because it was still too expensive. Sony had to kill the PS2 to move forward.
In re: Nintendo, of the Wii U's best games, and a lot of the Wii's best games, are on Switch now. In addition to new architecture, Nintendo also went from optical discs to cartridges. I can see them letting you play Switch carts on Switch 2, as long as the architecture itself is compatible. They were actually pretty good about backwards compatibility for a long time, especially with their handheld lines. They actually wanted the NES library to carry over to the SNES, but the realities of the market, which dictated hardware that compared to Genesis and TG-16 while not costing Nintendo an arm and a leg to manufacture and having to make customers pay an arm and a leg to cover, made that impossible.
The decisions to drop BC thus weren't arbitrarily made. They were the only reasonable decisions those companies could make at the time. Now that Sony has settled on an architecture for PlayStation going forward, it shouldn't be an issue, and as long as Nintendo sticks with tis architecture, it will likely have BC.
I agree on emulation. I'm not a fan of piracy, and emulation is a somewhat synthetic experience. When possible, I play games on original hardware (I own a Saturn and a Gamecube for their rare games). It simply isn't possible in all cases. I have considered building a JAMMA arcade cabinet.
