What will metalcore bands be like when they get older?

Saw KISS Love Gun tour in 1978, listening to Diary of a Madman and Screaming for Vengeance when they first came out, moved on quickly to Show no Mercy, Fistful of Metal, and Kill ‘Em All and everyone one of these bands came to bore me. There are not many post-hardcore and metalcore bands I don’t know and have listened to but I expect I’ll bore of them too eventually. And I don’t give a shit as music is truly progressive, one generations bands building and advancing on their own influences. Bands I started listening too just a couple years ago are already out of rotation. I won’t ever be that old man at a concert of old men, but an old man at a concert of 20 year olds…that is if I went to many shows, which I don’t, I just listen to music all day on my AK Jr and IEMs and my fellow grey hairs don’t get it.
