It won't.
Souls has been relevant, even successful, for a good decade at this point. The only devs who seriously took notes are all indie, and almost all of them have tried to out-soul Souls by making the base formula even less welcoming.
Let's face it, Souls wouldn't be as successful without the internet. Without coop, the games would be impossible for a lot more people. And you can bet your ass there isn't a single soul on the planet who 100%ed a Souls game without looking at a guide. The games can push the boundaries like they do only because there's online help to fall back on.
AAA devs and pubs know their audience. They know this is not what most people want, and wisely prefer making dumbed-down movie-like games with difficulty options rather than fully embrace a type of gameplay that would make their most precious IPs lose half their audience in the span of a single game, never to get it back.
