This is where the information economy starts to eat itself. If every message arrives pre-saturated with irony, critique, and self-awareness, then no signal can rise above the din. Warnings, reassurances, satire, and sales pitches collapse into the same register. The audience isn’t persuaded or misled so much as numbed.
It sounds like you are describing an unfolding future where all communication us ultra-processed.
I have posted about this a couple times, but ever since I saw Jon Stewart a while back describe modern propaganda as ultra-processed speech. It's engineered for reaction and engagement. It's like you said, everything collapses into the same register when there's a BOMBSHELL headline every day.
But the ultra-processed thing has been reaching much further into our media and culture than political speech for a while now. Like I dunno, everything that has half the people's faces buried in their phone in public.
I have two optimism-filled counterpoints to this.
Happy childhood memories are often much nicer than actually existing as a child. Much more concentrated. You already have the good stuff.
The only person stopping you from walking through the woods and finding cool rocks is you!
(insert caveats here about how adult life sucks for so many people right now and they don't have free time to wander in the woods. I know. It sucks. I can only encourage you to consider it a metaphor and find something realistic and rewarding that fits your life)
