Tears of the Kingdom is a miracle of engineering. Pokémon Scarlet and Violet and Hyrule Warriors: Age of Calamity did a lot more to show that the console isn’t keeping up with its own ambitions anymore.

That said I don’t think generations need to last the same forever because technological advancement doesn’t happen at the same rate forever. The PS4 isn’t being obsolesced by insufficiency, but rather by extravagance and marketing interests. Many games still run just fine on the PS4 to this day, even Jedi Survivor is being backported to it.
