Absolutely true. And I hope that would never happen... because I think I would rather chew off my own head than play D&D the way people on YouTube play it. Fun to Play and Fun to Watch are two totally different things. Lots and lots and lots of pointless talking about the most mundane things, having a full conversation with every random NPC the party runs into, roleplaying out every encounter with a merchant to buy every last provision... things that would usually be glossed over in most actual gameplay session I have ever taken part in. I suppose it could be a difference in playstyle between generations of gamers, but I think it's more about treating streamed D&D sessions as performative improv theater. The combat has been almost nonexistent, and while I wouldn't want to play in a D&D campaign that was nothing but total combat, neither would I want to play a campaign that was nothing but total roleplaying. But watching people roll dice and declare damage numbers probably isn't much fun for most people to watch.
