I think lasers are pretty wack when you think about them through this lens. A small, wand-like object in your hand can make light appear from seemingly nowhere. If it’s powerful enough it can set things on fire or blind people. Not to mention larger ones like laser cutters or the LLD, used to destroy missiles midflight. Thats sure to blow some feudal peasant minds

        It’s not even sound, because it doesn’t vibrate air molecules. If that were the case, it wouldn’t work in space for communicating with things like GPS satellites.

        They use light. Because wifi/radio/Bluetooth/etc are all just electromagnetic, which can be converted directly into light that is outside of the visible spectrum. The same way that a lightbulb works. And it only works because in higher bands most solid objects just sort of look like they’re made of glass. They don’t block those bandwidths, so the light is able to pass through them like a window. That includes things like your body. They’re just shining light directly through you.

        It’s akin to your phone and router flashing Morse code at each other with invisible flashlights.

      I remember finding out about wireless internet from an Intel TV ad. There was somebody with a laptop, browsing internet (probably an AOL page or something like that considering the era) sitting on a chair in the middle of a stadium, with no cable to be seen.

      I thought “well that’s stupid, I know you can avoid the power cable for a while if there’s a battery, but if he’s browsing the internet, there has to be a network cable”. But the ad ran over and over on TV, clearly insisting there was no cable, so I was like “hm wait…”.

      Eventually I read about wireless networks somewhere a couple of weeks later, and suddenly it all made sense.

      I somewhat disagree. As you said people weren’t idiots, they just lack the contextual understanding we have.

      Take a car for example. Even if you’d never seen a wheel, it would surely be easy to understand how it works just by seeing a car roll by. You may not immediately understand how its moving itself but I don’t think that means you would conclude its magic. You could think it’s biological, but honestly concluding that it’s a machine doesn’t seem that unlikely to me.

      Also the internet… I think most modern people just think it’s magic really.

        If you’ve only known stairs your whole life, a lift would seem like a teleportation device.

        I once talked to a guy on Reddit who had a version of this turned up to 11.

        I don’t remember the exact times so I’ll guess but it’ll get the point across.

        He boarded the New York Subway at 8:42am September 11, 2001, and got off at 8:50am.

        Dude was just having a normal day walking onto that train and the next station was in a totally different dimension.

        Agreed, we’re still intuitive creatures. An elevator may seem otherworldly for a moment but that feeling would quickly fade once you saw the cables and pulleys causing the cab to ascend/descend. It may be one of those “I’ve never thought of that but it makes sense” sort of revelations over “this is impossible”

          Especially because for most of history magic was accepted as reality by most people. So any aspect of the elevator that didn’t make sense to them, like the buttons and power, could be attributed to magic without much consternation.

          Nowadays most (non-religious) people think “well there must be an explanation, I wonder how they achieved that, I’ll get to the bottom of this.” But before public schools, the scientific method, and an understanding of the natural laws, regular folk would just accept the unexplainable as magic, ghosts, demons, etc. People accepted that Hermes’ shoes just worked, or that Jesus could turn water into wine.

          Humans are inquisitive creatures sure, but we’re also superstitious creatures who would often rather invent an explanation than admit we can’t explain it. And when you live in a world where even a rainbow or the stars are unexplainable, you get used to mythical explanations. You grow up with the people you love and trust giving you these explanations.

          It’s the outliers who had the time and disposition — Aristotle, Newton, etc — that we celebrate today for bucking that trend. But they were the exception, not the rule. Archimedes may have spent the rest of his days studying that elevator, but 99% of his contemporaries would have said “By Zeus what a marvelous gift from the gods”, stared at it for a while, and then returned to toiling in the fields and quarries.

      A lift and cars are pretty easy actually. People have messed around with mechanical tools since before the pyramids. They’d be amazed by a car for sure, but they’d understand it’s a complicated machine.

    Smart phones. Not even Star Trek could predict we would all be walking around with a slab of glass that is exponentially more powerful than computers that took up entire rooms, can communicate with others sub-second via voice, images, video, or text, can access the sum total of public human knowledge at the blink of an eye, and can guide you to any location with a map for everywhere you want to go. It’s really powerful stuff and it’s in everyone’s hands.

        Sir I have finished my report, here, have my entire table computer, I’ll go get another. I can see you already have six others, but this one has my word document on it.

    Well we’d all be burned as witches, so hopefully you are bringing people forward in time, not tossing them backwards. I’d expect my time traveler to be stunned by nearly everything:

    Flush toilet

    Electrical anything

    Telephone, speakers, TV

    I took a networking course in college and loved it but you still can’t convince me that radio isn’t magic. Even knowing the mechanics of it doesn’t help - it’s so freaking crazy. Fiber optic data transmission is such an awesome technology but even that doesn’t confuse me like radio, or broadcast tv.

    l can think of one magic-technology that appeared during my lifetime:

    E-Ink-Readers.

    I mean, script suddenly appearing out of thin air on flat, solid surfaces? WTF?

    I even studied enginering in the early 90’s and would not have been able to come up with a technological explaination if I had encountered one of those back then…

        But that’s exactly the point.

        E-Ink Displays would have been unable to explain for me from my thoroughly * informed * perspective as an HF and digital communications student.

        Active displays in one form or another had been around for 50 years or so at that time. So have been practially all base technology concepts of the much mentioned smartphones. Nothing magical about an optimized version, just extrapolation.

        But E-Ink? A * brand new * technology * without prior art * rapidly emerging from obscure theoretical concept to widespread use within just 15 years or so…

        I am actually still a little bit awed each time I switch on one of those…

    The more time I’ve spent studying and researching new tech, the more I feel like, even to people today, our technology is magical.

    I’m a medical diagnostic technologist. I understand how a CT and MRI machine work. They’re still the stuff of magic imo. A lot of people take these technologies for granted because they’re fairly prominent, but do you have any idea how a spinning magnet produces high quality, 3d images of the inside of your body? Very few people do. It’s still freaking amazing and ingenious when you do understand it. Remodeling a CT scan into a 3d render is similarly impressive. The amount of calculations that take place within the space of seconds would take years for someone to do on paper, and we do 25-30 patients a day in our one machine at my location.

    AI is making a big wave in my field too. Pretty soon we may only need radiologists to oversee AI rather than having to diagnose every exam themselves. AI on our consoles will be able to diagnose before we even send our images to a rad since they’re so good at pattern recognition. Their readings have shown to be more accurate than a radiologist in some studies.

    50 years ago we didn’t even have consumer computers. Now our computers can diagnose and type a pneumothorax more accurately and faster than a doctor who has spent his whole life diagnosing xrays.

      Nah, that’s not an actual plan that’s being implemented. It’s basically a thought experiment at this point. The problem with wireless energy transfer at that scale is that it takes a fuck ton of output power to generate a little bit of input power at a distance (inverse square law)

        Correction. It actually has been done.. A prototype has successfully demonstrated proof of concept.

        A space solar power prototype that was launched into orbit in January is operational and has demonstrated its ability to wirelessly transmit power in space and to beam detectable power to Earth for the first time.

        You are right about the efficiency, but since the amount of energy that can be gathered in orbit is so large, the small fraction that can be received on Earth could still be significant.

        For the latter one that wouldn’t be shocking. Opium poppies because widespread crops in the Bronze Age. I’ve even heard a classicist say that it’s theoretically possible that some Bronze Age healer in Egypt could’ve developed a secret formula for painkillers that was just morphine as the non poppy ingredients were able to be harvested using the trade routes and technology of the era.

        I think what might be more surprising is that we can consistently knock patients out for surgery without much risk of death and that we can stop people from dying after they’ve overdosed on opiates (though idk how hard it is to od on smoked opium).

        And in the medical field try explaining to a plague doctor that the bubonic plague is a mild inconvenience to all but the poorest people today and can be cured with inexpensive pills.

          Ok, fair enough. But I thought of another one- even into the 20th century, a huge number of battlefield injuries were automatic amputations. We don’t necessarily have to do that now in a lot of the same injuries.

    I’m 46 years old. In my lifetime, we’ve gone from being able to put half an hour on one side of an LP or cassette to being able to put a full album on a CD to being able to put a few hundred songs on an early MP3 player to being able to stream unlimited music almost anywhere in the world. That feels like magic to me.
