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.

It’s even cooler than lightbulbs, though (assuming we’re talking about incandescents) - you send electricity back and forth into a wire that’s just the right length, and (RF) light leaks out without it getting hot!

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 studied RF in college and it’s still sorcery. You wanna see a cool of the dark arts? Read up on QAM…

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.

You know what I was thinking is weird about this the predicted tablet computers but somehow they didn’t predict emailing the files to your superior.

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.

Although there are people where I work that actually think that’s how computers work.

TOS had them too. Also, 2001 A Space Odyssey also had something even more like a modern tablet. .

Dick Tracy predicted two-way wrist radios decades ago. My Apple Watch does that plus more.

We’re getting close to 100 years on Dick Tracy, the comics started in 1931. Not even sure that was the first wrist communicator in fiction TBH.

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.

Judging from my years in networking, not only most people, but many in IT see it as magic.

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.

I would take a pic of a middle-ages person with my phone, show it to them and tell them I stole their soul. Then I’d be beaten, hanged, burned, and drowned for witchcraft. Still, it’d be hilarious.
