By greatest invention I mean something that had big and positive influence.

    I mean we only have had fourth and things happen over time. So I want to say blue led but they existed before the century but just got the process such they can manufacture them. Native white ones are invented now but most white is using the combination method currently with the blue ones. Anyway if it counts I can’t imagine how much energy this has saved even over halogens for lighting and then for dispalys to. I would hate to think how much fossile fuel we would be using if we were still on incadescents and crts.

      I didn’t truly understand how much energy incandescent were burning. Grew up with nothing but those.

      One night my AC crapped out in my tiny apartment so I killed the lights except one in a far corner. The air was so still I could reach my hand out and sense the heat from a 60W bulb.

    Hard to quantify, but stuff like PrEP (a drug used to prevent HIV infection) has probably saved a staggering number of lives across the globe, same with the yearly influenza vaccines.

    For a more personal one?

    I’d say the innovations to bikes, which have been staggering since 2000. Downhill mountain bikes have had staggering changes that make them lighter, faster, stronger, and way more stable, and they look dramatically different to their 90s counterparts. Stuff like dropper posts, modern full suspension, tubeless tires, disc brakes, and massive cassettes make them incredible. You can roll over a cantaloupe-sized rock at 20mph and the bike will just take it without you being ejected over the bars.

    Ebikes have totally changed the calculus in hilly cities, even in flat ones to some extent. Being able to effortlessly bike 45 miles and not be totally thrashed the next day is such a gamechanger, it’s actually beyond belief. My car has been largely collecting dust because most trips day to day are under 45 miles. And it takes pennies to recharge vs $90 or so to refill the tank.

    Bikes already help take tons of cars off the road worldwide, but ebikes could really help extend people’s ranges, particularly if they would normally drive otherwise.

      getting from my house to my office on my old road bike used to take 45 mins and I’d be sweaty when I got there, and the idea of 45 mins uphill after work used to make me wanna off myself. Since I got an e-assist its 25 mins and I’m like lah de dah meep meep

        Dude, same. My e-bike is hands down my favorite addition to my life. Where I had to deal with the train or the traffic and the waiting and the crowds, now I hop on my bike and cruise lah dee dah meep meep but when I am running late for work I’m all like eeeer vroom vroom skrrrt and I bomb down the bike path like aw yeah. And I’m honestly rarely late anymore because I get everywhere in about half the time it would’ve taken me otherwise.

              I totally agree. But the question was about inventions not mass adaption.

              That’s like saying Henry Ford invented the car because the Model T was the first widely available one.

                  That’s going to be a tough one to call. Nokia Communicator had diary (calendar), web browsing and email features in the 90s. You could also tether off it, but it was dialup and most phones could do that.

                  That was pretty much the definition of a smart phone at the time.

              It may depend on your culture, but Blackberry and Windows Mobile phones were both fairly common in business circles years before iPhones.

              The iPhone was an incremental advancement, not a major invention out of nowhere. The first iPhone was actually pretty crap compared to some models on the market. It wasn’t until the 3G model that iPhones took off.

            Waze and many of the companies you listed are not BDS targets, for good reason:

            The global nature of today’s economy means that there are thousands of companies that have links to Israel and are complicit to various degrees in Israel’s violations of international law. However, for our movement to have real impact we need our consumer boycotts to be easy to explain, have wide appeal and the potential for success. That’s why globally, while we call for divestment from all companies implicated in Israel’s human rights violations, we focus our boycott campaigns on a select few strategic targets. We also encourage the principle of context sensitivity, whereby activists in any given context decide what best to target and how, in line with BDS guidelines.

                https://craft.co/waze/locations - it’s headquartered in Tel Aviv. Boycott it.

                Maybe some horrible massacre happened there once, but that’s like the heart of 1948 Israel, not some illegal settlement in the West Bank.

                “The modern economy is very global and interconnected” is a cliché - too vague and obvious to guide action.

                Maybe, but it is an esteemed, Palestinian lead organization employing that cliché and providing good justification for it. I will be giving the guidance from BDS more weight than yours, @frightful_hobgoblin@lemmy.ml.

      Many things that were conceptually conceived in the 20th century didn’t become viable until the 21st, such as OLED, VR and AR, raytracing, telesurgery, a whole slew of types of artificial organs, a gigantic amount of miscellaneous advancements in integrated circuit fabrication, alternative vehicle fuel such as methane, hydrogen and rechargeable batteries; maglev trains, innumerable safety improvements in aviation, mRNA vaccines and so on and so forth. I don’t think it’s fair to credit all that stuff to the 20th century, unless someone somewhere saying “be real cool if we could do that” counts as inventing something.

        OLEDs were built in 1987 I saw my first VR demonstration in the 90s (and it wasn’t cutting edge then). I saw my first AR demonstration then as well as part of an undergraduate engineering fair. And so on. I just looked up maglev trains - in commercial use since 1984.

        I don’t disagree that there hasn’t been refinements, improvements, or commercialization of technology, but there hasn’t been a technological leap or invention that I can think of in the 21st century.

          To be fair, there’s only been 24 year’s of 21 century. Most things you gave listed happened at the end of the 20th century. But also the question is somewhat self negating - we won’t know what’s the greatest invention until we see it working great, but it takes much more than 24 years to take an invention from concept to consumption. For example computational biology is kicking off. Computer aided dna generation started in the past 24 years. But it’s so new few people think about it. Just like no one thought of internet as the greatest invention in the 70s… it was just too new

            You’re not wrong. But there are counter examples. I was going to use the example of the jet engine in my last answer as a true paradigm shifting development that had immediate impact. And in the mid-century period too! Or the first powered flight occurred in the first decade of the 20th century and had an immediate impact. The transistor and solid state electronics would be another example.

            So let me flip it around and say we’ve had a quarter century without a major technological breakthrough. There’s been progress, but it feels incremental. I spent a night with a physicist a few years ago who was arguing that progress is slowing because we are still relying on the exploitation of Newtonian physics. There are a few technologies that have made the leap to nuclear physics. But we’ve had the basics of quantum physics for a century now and haven’t been able to exploit it in a useful fashion.

              Good point! I wonder if we’re spoiled by computer invention though. Would be interesting to compare preWW2 invention rates and now. I suspect computers just made everything else easier, but now we’re back to hard problems

          3D printers were a 21st century invention, I think.

          Quadcopters and other multirotor designs resulted in an incredible leap in affordable cinematography, racing applications, rescue, mapping, and warfare.
