Looking at the WotC design team, they have quite the diversity in terms of generational representation: Perkins started playing in the early 80's, whole MacKenzie de Armas started playing D&D because of watching Critical Role and is part of writing the new Core rules now. That's the sort of thing that allows them to service a variety of people, even if they keep on target.The actual demographics of the game are besides the point. However it breaks down, I still haven't seen anyone explain why they think they are ignoring us older gamers (however many of us there are).
What does catering to old folk even look like? What is it you are looking for that they are not doing?
As someone pushing 40 soon enough, I don't care that I like things primarily aimed at teens and tweens: that's just life.
