can I have a couple of recommendations of newer bands (i want to listen to people who will still be around in a decade)

I’m recommending based on the list on your post. These are not really “new”, but are newer relative to your list and are going pretty steady:

Gojira
Haken
Animals As Leaders
Leprous
Jinjer

I’d like to add Opeth to this list too. One of my favourite bands.
Came here to say Gojira as well.
Animals as leaders are my favorite to listen to when working out and building Magic decks. Those fellas tickle the ears.
I liked leprous and jinjer... Thanks

(every music agent would love to know which bands will still be around in a decade)

But based on age most of who i listen to will stop

I'm mostly a punk and emo guy, but see you're more of a hard rock metal guy. I am a fan of Protest The Hero. I feel like it will be up your alley.

Noticed the Saxon album cover; the lead singer's son also has a band.

They describe themselves as alternative rock/grunge/schizoid blues with the punk attitude of the 70s.

Check out Battle Beast. Strong 80s vibe, very theatrical. Their most recent album, circus of doom, is quite good imo, and they sound even better live. Highly recommend!

They are pretty damn good thanks
- Enjoy! If you get a chance to see them live, it's very worth it!

A few recommendations

Grand Magus is closer to the Ozzy style, especially if you're into the Black Sabbath stuff.

Cauldron are a really solid classic sounding heavy metal band.

I would love to recommend Scorpion Child But it's been a decade since they've released an album so I'm not sure what's going on, there.

Haunt are my favorite modern band who I think fit your style. These guys just keep getting better so far

Bands stay around when they have support. If you want bands to last, listen to them and see them play.

Lorna Shore, August Burns Red, Bad Omens, Bury Tomorrow, In Flames

Judging by the image, their concern is more that a lot of the bands they currently listen to are simply of an age that they've retired or died. It's not a lack of fans that stopped Black Sabbath from playing, it's that the members are well in to their 70s
In flames is good thank you
- Well if you like Amon Amarth, Arch Enemy and now In Flames just go down the melodeath rabbit hole:
  
  Dark Tranquillity
  
  At The Gates
  
  Soilwork
  
  The Halo Effect
  
  Majesties
  
  And then you've got the whole deathcore scene which has been massively influenced by melodeath.

It's tricky because there is so much classic thrash on here, but that genre died and was revived and then died again. If you get a taste for death metal or some of the other more contemporary extreme subgenres it'll be easier to follow current bands and see them in the future.

Here are a few modern recommendations you might like:

Unto Others (fka "Idle Hands" ) - Mana
Tribulation - Down Below
Blood Incantation - Hidden History of the Human Race
Worm - Bluenothing
Bell Witch - Mirror Reaper
Obsequiae - The Palms of Sorrowed Kings
Havukruunu - Uinuos Syömein Sota

I don't have any recommendations because you listen to very different music to me, but why does the band being around in a decade matter?

I like live music and I'm 17. I wanna see shows in a decade
- Just go to shows. Stop worrying about if they're perfect or if they'll be around forever. Just go and get out of your comfort zone sometimes. Nobody here can tell you who will be around in a decade. None of that really matters though if you stop worrying and just go and support musicians you enjoy as directly as you can.

Angelus Apatrida

Sabaton has been around for awhile. They're a Swedish metal band that sings about history, battles, and the heroes that took place in those battles.

Three bands from the UK, Florence Black, Margarita Witch Cult & Tailgunner 🤘

Nervosa and Enforced if you’re looking for some newer thrash metal.

I know you said newer bands but you might also like some other older stuff like Pantera, Biohazard, Sepultura, Testament, Corrosion of Conformity, Type O Negative, Overkill, etc.

I'm a simple metal head: I see Iron Maiden, I see Megadeth, I upvote.

Edit: almost forgot — I see Arch Enemy, I upvote.
