What's happening in the hardcore scene in 2023?

I typically pose these sorts of questions to Reddit, but Tildes hasn't failed me on anything music related. We had an incredibly successful prog metal thread a couple of weeks before, and I'd love to have one on hardcore punk.

I have general questions about hardcore like:

• Who are the biggest names in hardcore of all time that still tour and write music today?
• Who are the biggest hardcore bands that have started in the last decade or less?
• In 2023, is it even useful to talk about hardcore as a distinct genre separate from metalcore anymore?
• Does any metalcore meaningfully exist in the hardcore scene? Is there any metalcore scene that embraces the punk ethic of hardcore?
• If a through-and-through hardcore band uses elements of metal in their music, are they now metalcore? Are you no longer punk if you use breakdowns?
• What should people know about the hardcore punk scene?

I don't know enough to know which of these questions are stupid or cringe, or what the best questions to ask are. Feel free to answer questions, ask questions, or share your knowledge of the scene with curious minds.

As always, I greatly appreciate your feedback!
