So it may just be a generational thing; im apparently a good bit younger than you, and "weaponizing latent psychic potential" to me is an explanation on par with "Veidt can catch bullets because he's actually a spirit medium channeling kung-fu masters." It's total nonsense with massive implications that should radically alter the setting but doesn't.
I prefer you saying you're young over saying I'm old, so thank you for that!

It likely is the case and I do think there is a difference in what triggered people's disbelief forty years ago over what does now. It's something I've become increasingly aware of when seeing people watch or read the media of generations other than themselves. The prevalence of belief in psychic powers has changed sharply. Of course I'm seeing it through my own lens of being in a different age group than I was back then (obviously) so I'm trying to allow for that but even so. And it's funny you bring up Kung Fu masters because I remember a guy in my Dojo asking the sensei if he could fly. Which is really the sensei's fault for being the sort of dick who tried to cultivate a mystic air about himself (I found a different school) but even so - you found a tonne of people, and I mean adults, who believed fully in martial arts masters focusing their chi at someone and blasting them off their feet without contact. Stuff like that. Of course such people still exist but psychic powers, spoon bending and so on. You may have read how in Victorian times people loved the occult, spirit mediums, all that stuff. It's never gone away and it takes different forms and it waxes and wanes. I remember people having serious conversations about astral projection as a group. I'm probably building this up more than I ought, it's not like everyone believed this stuff. But I do feel quite strongly that when Watchmen was released the idea of psionics in it was nodded along with more familiarity than it is today because it was one of the tropes of the time.
There's always something - one generation it's faeries at the bottom of the garden, a few down the line it's grey aliens and rectal probes. They reflect the spirit of the time and the fantasy settles into whatever nooks in human experience it can find. Like the God of the Gaps on a small scale. No room for faeries in flowers anymore. But we have science - maybe there are aliens in saucers. Hmmm, we're filling in those gaps with our awareness of just how great the distance actually is between stars, maybe they're actually extra-dimensional beings from next door. Knowledge expands and human fantasy flows to where it isn't. For a time it was psychic phenomenon. It's this era that produced Carrie, Scanners, The Fury, Jedi and so much more. And in the real world the dude asking my sensei if he could fly and a bunch of people trying to summon their chi to sense attacks blindfolded.
Anyway, I understand your position. It's well-articulated and supportable. I can't refute it, I just think it doesn't apply as widely as you think. Whereas I am sure you long since got my point and you have every right to feel I am the one that is wrong. At this point I view this as us chatting about media, not arguing.
A related thing I've often observed generationally in media is understanding of violence. You watch old post-War movies, Noir films, etc. and the violence is short and effective and it has to be because the audience was more familiar with violence back then. So Sam Spade socks someone in the jaw and they fall back and sit down stunned. Not only the "realistic" stories of the time but the fantastical ones as well. When black and white Flash Gordon has a fight it's still short and realistic even if it's taking place on a rocket ship. Over time that changes, but even with Raiders of the Lost Ark era, Indiana Jones is getting socked in the jaw and knocked out, a single bullet is deadly and a small revolver is still a way to put threat on the screen. I honestly think an adult from the 1940s would regard most modern action movies as mad pantomimes, like us watching some over the top Chinese Theatre show. Performative, funny, but not something to suspend your disbelief over. But modern audiences, mostly less familiar with actual violence, love to see Tony Stark (bringing it back to Marvel here) get punched in the face and body a dozen times and then get up and keep fighting. We're just... unfamiliar with the subject matter these days (for much of the audience).
Had a superhero weakness, too!
But I'll see your Judges 13-16 and raise you Epic of Gilgamesh, tablet #1.
We should stop though before we end up re-recreating Samual L. Jackson's speech from
Unbreakable about comics just being a modern form of the same mythic stories. Or not!
