Remember standing in the checkout line at a grocery store in the pre-Internet era and seeing the tabloids (not so much the celebrity gossip ones, but those that were full of UFO abduction stories, sasquatch attacks, miracle diets, and so forth), and thinking "Imagine if the people who live for this stuff were in charge of the world..."
The joke was too frightening to be funny, but since it was literally impossible---a means to accomplish it wasn't even
imaginable---it always brought a smile.
Well, thirty years later, here we are. The Tabloid Believers were provided with something called Social Media, and now virtually all societal and cultural direction is controlled by them. Product makers, service suppliers, industry leaders, policy makers, and the educational system dare not ignore, insult, or challenge their beliefs. Doing so can cost you everything. Your business, your job, your social life, your office. It's called "canceling". The 21st century name for the "She's a witch!" dynamic of the Dark and Middle Ages
In short, the ignorant and irrational are now in control of the bright, creative, and industrious people who once led society.
The danger of that upside-down dynamic was addressed in America's early years by only allowing landowners to vote. (Back then, owning land was the strongest indicator that someone was both clever and industrious).
The slide toward allowing irrational people to drive the bus began when the land-owning requirement was removed with a constitutional amendment, and culminated with the invention of total coverage Internet and always-on smartphones.
It was 100% predictable once the technology had been developed, but the danger was disregarded and/or ignored at every level where it might have been stopped by those who profited from it in the short term.
Which is
also 100% predictable, because that's how humans are wired.
Short of another Carrington Event, it won't end, either.
Regarding the "Yes, but the pendulum will swing back to sanity eventually" argument, consider that it takes many tens of millions of dollars and thousands of man-years to build a skyscraper, but only a few seconds to destroy it.
And there's no rewind button.
The same is true of virtually all evolved, complex things.
The society we grew up in was the product of many decades of trial-and-error, and incalculable investment of both money and labor. It wasn't perfect, but worked well enough to put a man on the Moon, help defeat the Third Reich, prevail over Stalin and the Soviet Union, and become the preeminent power on Earth
while retaining personal freedom for its citizens.
Destroying such a construct---such a
machine---is as conceptually simple as dropping a ball bearing into the spark plug hole of a running car's engine. The energy of the destruction doesn't come from outside, but is supplied by the engine itself.
In short, "the pendulum swinging back" doesn't apply to the situation. A realization that you went too far certainly does, and wishing you could fix it as easily as you destroyed it certainly does, but the Second Law of Thermodynamics will only laugh.
