Has rock music hits its creative peak?

Thread inspired by a conversation I had with SharksFan99 recently. Do you think that rock music has reached its creative peak?

Over the past few years, there have been several music acts coming out trying to keep the rock genre alive, which is all well and splendid given the genre has been dormant in the mainstream since the tail end of the '00s decade.

Examples of this include Greta Van Fleet (classic rock), White Reaper (garage rock) VOIID (grunge), as well as acts to revive emo and "butt-rock" as well.

However, once catch to all of this is that these music acts are only reviving sub-genres of rock that were successful in years past instead of creating new ones.

Granted, the reason they are likely doing this is because these subgenres which they are trying to revive already have an established following to them, whom will have an interest in that type of music, which is a much smarter and less risky avenue to take compared to starting from scratch with not only a new genre, but also trying to create a new fanbase for said new genre, which is a deed doomed to failure in an era when rock music in general is not mainstream anymore.

However, if all of these acts succeed in bringing rock music back into the mainstream, would that be a good time to start from scratch with a new sub-genre, and if so, how experimental can they get when creating this new genre as well as getting a song on their album on the radio, without the song at hand being a Bohemian Rhapsody or Black Parade knockoff, or the album being a Sgt. Pepper knockoff, or their new genre ending up like all those "core" subgenres?

Now, if you've been following music back in the late '00s and early '10s, chances are you may have heard of bands such as Black Veil Brides, Asking Alexandria, Attack Attack!, Escape the Fate, Falling in Reverse, Blood on the Dance Floor, BrokeNCYDE, The Millionaires, 3OH!3, Dot Dot Curve, iwrestledabearonce, and Design the Skyline, amongst numerous others, which had a following but received tons of backlash from music critics everywhere, and may have also heard these bands be referred to as under a certain "core" genre.

The "core" suffix in these genres references hardcore punk, typically screamo, and there are actually numerous sub-genres with the "core" suffix which mix a certain genre of music with screamo and other hardcore punk variants.

These include metalcore, deathcore, thrashcore, nardcore, mathcore, grindcore, christiancore, digitalcore, jazzcore, crunkcore, crabcore, nintendocore, easycore, and there's even bluegrasscore (Blood & Banjos), ans well as bands that can be considered reggaecore (Skindred). That's a lot of core! You could make the argument that all of this means that hardcore punk is a heavily versatile genre if you could seemingly create infinite "core" genres by just taking any music genre and adding screamo to it, (ambientcore, anyone?) but really, none of these sub-genres are really popular outside of niche circles. Granted, a large reason for that is because screamo music and hardcore punk in general is not versatile audience-wise, but also, most fans of one core genre are fans of another core genre as well, since the core (ha! pun intended!) style of all these sub-genres are mostly the same, and again, for the most part, all of these core genres are underground, with only a few singles from a select few of these genres having mainstream success. Any newly created "core" genre would just become one of the bunch, and would only have a small-level niche following at best.

Now, rock music that isn't hardcore punk or metal (I'll get to metal in the next paragraph) has more potential to reach a wider audience, but you still need to make your radio hits presentable to an average person who is just listening to their car radio trying to drive from Point A to Point B, and that is difficult to do when you're trying to experiment with creating a new sub-genre of rock music.

I think there is potential for a new sub-genre of rock to be created, but it's still a long way from becoming a mainstream reality at this point.

As for metal music, there's tons of potential for experimentation there, since metal as a whole is relatively artistic to begin with, as well as because metalheads are one of the few factions of music fans left who prefer albums over singles, and there are plenty of experimental metal bands I do enjoy who are very experimental and creative in their musical structure. But again, none of this will ever become mainstream, as metal music is inherently a niche genre.

Anyways, what do you all think on this subject at hand?
