To counter your anecdote with my own, not that I've seen. My Gen Z sister and her cohort of Z friends have a "chosen family" dinner every weekend where they come over and cook. One person takes lead, the rest help as needed, and almost every single one finds recipes and learns techniques from Instagram or TikTok.

They've come up with some crazy good dishes that I wouldn't have stumbled across via traditional cookbooks and more millennial + oriented websites. My sister also has much better and more varied techniques than I ever got the old way, learning from mother and other relatives.
