People Break Down The Scariest Inventions Mankind Has Ever Created

Ever wanted to freak yourself out? Stay up late at night and read Hiroshima, journalist John Hersey's account of the Hiroshima nuclear bombing and its immediate aftermath. It's 31,000 words––originally filling an entire edition of The New Yorker––and it never fails to send a chill down my spine. The piece, later published as a bestselling book, is a frightening piece of journalism about one of mankind's most frightening inventions... perhaps it's most frightening.

People shared their opinions after Redditor Illurinatil asked the online community,

"People of Reddit, what is the scariest thing you think mankind has ever created?"

"You can't see them..."

"The most terrifying inventions are biological weapons. You can't see them and you die horribly. In the best case, you die within minutes; in the worst, it can take hours or days. Or you don't die and there are permanent damages to you."

The silent killer.

Reading about the Ghouta chemical attack is bound to ruin your day. We apologize in advance.

"Chemical weapons by far..."

"Chemical weapons by far because the effects are limitless and you can engineer the fallout to be global."

"A vicious cycle..."

"A vicious cycle where we have the technology to solve our problems but can't because not everybody can agree on it."

Coolius69

We're doomed, aren't we?

Yeah... we totally are.

"The idea that..."

"Adversarial thinking. The idea that "we are right and they are wrong." This is how every war begins."

"I'm honestly..."

"I'm honestly going to have to go with social media in its current form. Nuclear weapons have chains of command and are kept under lock and key. Some private cannot initiate a nuclear strike but any nitwit can hop on Facebook, Instagram, etc. and fall into the rabbit hole of extremism, believing whatever some @ss tells them due to lack of critical thinking skills, people who know how to exploit social media doing just that, and so forth. And this has happened to millions of people.

I honestly think social media has been a net negative to humankind and that, if it had been invented in the 1940s, we would still have polio crippled people being placed in iron lungs every year."

DeputyCartman

"Nukes are..."

​"Nukes are what kept the planet at peace for the majority of the world based on the understanding that if you get turned to dust in a second you are considered the lucky ones on the receiving end. It is by far the scariest thing mankind has ever created."

ghigoli

Mutually Assured Destruction has indeed kept the world safe... but what happens when someone gets a little too scary and cocky?

Probably shouldn't think of it. I need to sleep tonight.

"I just saw..."

"I just saw a video of a robot controlled by neurons from a rat's brain. So that's alarming."

owmyfingy

"The scariest thing..."

"The scariest thing mankind has ever invented is still a secret because if they told us we wouldn't be able to sleep."

Blacklolipop

"We don't have very much..."

"Antimatter. We don't have very much of it, but the very idea of a substance that can annihilate matter is insane. For that matter, the colliders that can make it. The physics involved are terrifying."

Rainbow_Dash_RL

We'll never sleep again.

Sorry if you had a nice, leisurely day planned. Did you really need another reason to think that humans are horrible? To be fair, they make it so easy.

Trump Claims The White House Was 'A Sh*t House' When He Moved Back In—And Everyone Had The Same Response

MAGA Republican President Donald Trump has made significant, controversial changes to the White House since he took up residence for his second term on January 20, 2025.

The renovations in just over one year include installing pavers to replace the grass in the Rose Garden, adding gold decor throughout the building and especially in the Oval Office, renovating the Lincoln bathroom to add marble and more gold fixtures, adding gold signs for White House features like it's one of Trump's resorts, hanging a plethora of massive portraits of himself in gaudy gold frames, and demolishing the entire East Wing of the building to erect a self-described monument to himself, an unpopular golden ballroom that will dwarf the rest of the building.

MAGA fans who signed up to get Trump Mobile T1 phones nearly a year ago are furious after learning there's no guarantee they'll ever get the phones they put down deposits for—and that these same deposits are now being described as merely a "conditional opportunity."

When asked about her future political ambitions during an appearance at the Institute of Politics at the University of Chicago, New York Democratic Representative Alexandria Ocasio-Cortez was notably candid, saying her "ambition is to change this country," as she ripped a Washington Post editorial that tried to knock her down a peg for her take on the morality of billionaires.

The progressive is not currently considered the frontrunner in early 2028 Democratic primary polling but some surveys suggest she has already emerged as a serious contender in what is expected to be a crowded field.
