This might be me; I am older and have less time. The bar to novelty in my life was a lot lower in my late teens than it is now. But I can't shake the feeling that "something" has changed in the world around me. Every social medium, from the follower-only Mastodons to the heavily algorithmicized Twitter FYP is angry at something or dunking on someone.
(N.B. Sometimes I wonder if this is the nugget of truth behind the wisdom of having kids. That at some point humans become inflexible and recalcitrant but the act of having kids ties your own mood and outlook to the future of humanity as a whole rather than your own crotchety self.)
