I'm a younger millennial, I'll be turning 32 this year.
I feel for you older players who feel disenfranchised. Like
@Belen who had to struggle in an era where where you'd get bullied for liking D&D. I never experienced that. I went to a high school where I was friends with some of the more popular kids in school because they were in the marching band with me. In the late 2000's to early 2010's being nerdy was cool. I constantly had a rotating cast of kids coming to my house to play D&D. We used to play in the lunch room at school.
I feel for the gamers like
@AstroCat who feel as though they are actively being pushed out of the game by the company who makes it. It does often feel like art direction and design choices are made with my generation in mind.
On the flip side however, the "Old Guard" hasn't always been the most welcoming bunch. There's been a lot of gatekeeping.
Thankfully there are plenty of gamers out there like
@bloodtide who while apprehensive at first was willing to look past their biases and take on a gaggle of teen girls, and ended up having a good time and cultivating a new crop of life long gamers. I've had so many female friends and acquaintances have horror stories about trying to play D&D and being subjected to the grossest stuff.
Or
@Warpiglet-7 who didn't turn their nose up at their kids for wanting to play a goblin, or a... fruit thing.. This has been such a contentious point between generations. To some people it's still controversial that Tieflings became a player race. I've been at tables where someone wanted to play something that's really not even than weird.. Like a goblin or a kobold, and they were met with an attitude akin to: "No. You'll play a human, a dwarf, or an elf, and you'll like it.. And you should consider yourself lucky you get
that many options. Back in my day you'd get penalized with a level cap for wanting to be something weird."
What it comes down to is that I think younger gamers and older gamers are two pillars of this hobby, and both are required. One may not feel like it needs the other, but ultimately they both hold the weight. I'm glad that WOTC seems to be trying to cast a wide net with this revision, and hopefully it can facilitate more bridging of generational gaps.
