If you ask me? Mobile/WiFi internet… The way and amount of time we use our phones had changed A LOT since their diffusion. I guess the release of the iPhone changed our idea of what a phone is too
Edit: when I say modern world I’m referring to the last 50 years. So stuff like “the electricity” or “the telephone” doesn’t count.
Chemical fertilizer. World population would probably be half the size without it and starvation rates much higher.
One of the guys who invented the process for large scale production was Fritz Haber, to make explosives and chemical weapons. He’s also responsible for using chlorine gas on the battlefield in WW1. His wife was a chemist and an activist, who shot herself in the heart after learning about his involvement. Haber left within days for the Eastern Front to oversee gas release against the Russian Army.
He ended up saving more lives than he destroyed, but what a story.
There’s a really good section on him in the book, How to hide an empire - a history of the greater united states.

Transistors is the defacto answer. We wouldn’t have anything we have now without them.
Oh you say but what about (this thing) that doesn’t have any in it? The factory it was mass produced in runs on transistors.
Going down the list of comments in this post:
Telephones. Always had transistors.
Internet. Obvious.
Coal. Everything from the trucks to the converors, to the systems that track production, and all the transportation involved after uses them.
Washing machines also use them even if they’re not the stupid “smart” machines people buy for some reason.Edit. If you’re in anyway curious about transistors here’s a new video from Asianometry about them:
https://youtu.be/k8cdByDa3oA?si=5B4tgJjP7X7jIuhTSomething worth repeating is that transistors are a direct application of quantum mechanics. Quantum physics isn’t a metaphysical thing about half dead cats and working only on a few ultra cold atoms. If you want to explain how a piece of silicium can be conductive or insulating depending on it’s polarisation you need… Quantum physics.
Holes and dots.
its* polarization (or polarisation, in your part of the world.)
It depends on what you mean by piece of technology I guess, since what we have now is a culmination of thousands of awesome tech over the last few hundred years.
If I were to choose one thing, I’d say the telephone. It’s the predecessor to the internet, and suddenly communication between people was instant rather than messages that’d take forever (or morse for the places that had it).
It probably changed the world forever, being able to talk to someone in a completely different country and share something quickly.
I can’t call in 2024 the era when telephones came out “modern” anymore
To be fair, you didn’t say it had to be a modern technological invention, just that it impacted the modern world
Tobefaaaaair
In the last century? The diode, aka the P/N junction and every variant that has been created ever since.
Recently? Capacitive touch screens are by far the most significant change.
The most?
Fire.
The best guesses right now is that our ability to use fire–and eventually create fire–allowed us to evolve the brains that we have now, because cooking food significantly decreases the energy needed to process it, which allows more energy to be used by your brain. And our brain burns a lot of calories. Cooking food is essentially a preliminary digestion process. Without our brain, the modern world as we know it never exists. Hell, we never even evolve past troops of apes.
Cars shaped city planning, housing and by consequence our lifestyle, making us more dependent on them to get through your day. You can see it expecially in European cities that were built in medieval/reinassance times: if you live and work in the older parts you can totally do without a car. If you move a few kilometers out, not having one becomes a real handicap
You can see this in the U.S. as well.
In many parts of the world, though, I wouldn’t say cars per se, but definitely public transportation. A lot of people can’t afford cars in the world, and they still benefit from the invention of the internal combustion engine.
The nuclear bomb. Even before we nuke ourselves into extinction, it has had a profound impact on geopolitics. Imagine the huge conventional wars we could have had!
Nikola Tesla’s alternative current.
Social media. And not in a good way
I agree.
OPs answer of saying that WiFi and phone Internet changed the world is correct, but it’s not specific enough or the full truth of the matter.
If we had the Internet and modern phones but the only sites that existed were those from 2002, we’d be living in a very different world.
Mobile Internet is the enabling technology, but if social media didn’t exist we’d probably leave our phones in our pockets most of the time.
Facebook existed way before mobile internet was everywhere.
Sure, I was there then. I was on Facebook right in the beginning, when you needed a university email address to even sign up.
So that’s true, but it’s also true to say that early Facebook wasn’t the same as modern Facebook. Early Facebook was - as the name suggested, a place to connect with friends, share pictures and plan events. You’d probably check it once a day to see what was happening, but that was it. And your home feed would be a direct and unfiltered view of what all your friends posted, in the order they posted it, without bias. And you could easily catch up on everything that had happened and then you were finished.
It’s the birth of the algorithm and infinitely scrollable tailored content feeds that really defines what social media has become.
This and mobile Internet have really gone hand-in-hand. The algorithm has made us want to be scrolling all the time, and mobile Internet has made it possible .
And your home feed would be a direct and unfiltered view of what all your friends posted
And it was a feature added later when they wanted to compete with Twitter. Prior to that, no home feed. Just profile pages, a la MySpace. And it was glorious! It was so much fun to leave wall messages to friends, and see whatever others have posted in them too.
When the newsfeed came about, I remember thinking “I don’t like it. It’s stupid!” mainly because I knew it was a reaction to Twitter. Of course, I got used to it eventually.
But yup. Facebook back then was a neat tool. Not the cesspool that’s been for the past 10 years.
