    Steam.

    Always impressed that a nuclear power plant actually, doesn’t use much nuclear physics/engineering but is mostly a steam machine (with a top notch turbine)

    I’m not surprised at all since I use them every single day, but the pen and paper have yet to be rivaled by anything digital. At the very least, in regards to:

    • portability: available in any size one may fancy, only a few grams.
    • autonomy: a notebook needs no battery and offers weeks or months worth of storage depending how much you write or sketch (certain models can even be refilled),
    • ease of use: put pen(cil) onto paper and write, or sketch + no upgrades, no bugs, no crashes.
    • privacy: no tracking, no spying by any corporation. No ads, either.
    • low cost: I’ve yet to find an iPad with its Pencil at the two dollars I spend on my cheap notebook and cheap ballpoint, or pencil.
    • Sturdiness: I can (and often) sit on the notebook I store in my jeans back pocket, I often use it under the rain too.
    • Low attraction to thieves: I can use it anywhere without risking attracting attention from potential thieves. I can also let my notebook alone in any public places, chances are no one will even consider stealing it: it’s just paper. Try doing that with a digital notebook, be it a tablet or a phone ;)
    • Versatility: I can write (errands, novels, plan to conquer the world, a poem for my spouse), sketch (bad or good sketches), draw a map, play some games, make paper planes or origami, and even share info with anyone by tearing of a sheet of paper from my notebook (that won’t break it) and give it to that person.

    Yeah, I think it’s kinda obvious I do like my cheap notebook and pen, a lot more than I will ever like that corporate and government spyware that disguises itself as a smartphone and that I’m expected to be using and carrying with me everywhere I go ;)

      As a programmer it makes me livid being forced to poorly hand fill the paper only to see someone at the desk enter it all into a computer.

      Also, couldn’t I have done this online beforehand?

        You forgot the nth generation copy of a copy of a copy that has no true blacks, just these weird grey pointillism bands that are so askew your basically writing at an angle.

        I also have some horrendous carpal tunnel syndrome, if I’m filling out something on a clipboard, my already rusty handwriting is going to rapidly degrade even further.

      I saw an urgent care (in the US) using iPads in a thick case and I think an apple pencil for signatures? (or maybe I misremembered and just used my finger to draw the signature).

      Everything is digitized now, really bad for a political dissident with depression since you can’t openly talk about being a dissident especially when the country is under autocratization.

    Fax machines!

    They were invented long before the computer or modem, with the original patent being issued in 1843.

    They seem wildly outdated, but the ability to replicate the signature (iirc) led to faxes being accepted as legal documents.

    This speaks more to the underlying usefulness in earlier eras, but it’s still wild to make a phone call that leads to a printed document.

      It may have started with the ability to replicate signatures, but even during the internet age, fax does have one interesting advantage.

      It uses a dedicated circuit to communicate rather than using packets.

      By that I mean that two fax machines that are connected to send a fax are electronically linked together in a dedicated circuit for the duration of the session, and all the data takes the same path.

      This is in stark contrast to an email, which is split up into packets which may take quite different paths to reach the other destination.

      At my old government job, we had a fax machine because it “couldn’t be hacked”, so we would only accept certain documents via fax. Is this true? I have no idea. It was even more questionable when we switched the fax line to digital and received all the faxes via a software program on computers. Is THAT “un-hackable” too? No clue.

    An easy answer is pagers in hospitals. I know it’s because they’re simple RF technology, and work reliably in cinderblock buildings. But given how advanced so much of our medical equipment is, you’d think there would be a different system. Granted, that system would almost definitely need updates and have potential downtime/crashes, which you cannot afford in that kind of environment

      There was a good episode of Planet Money where they interviewed some doctors who were trying to get rid of beepers at their hospital. Basically during testing, it was found that when using an app to send messages to doctors, it was almost too simple and non critical messages were being sent to doctors. This was creating a lot of noise and causing them to be overwhelmed and ignoring the notifications on the phone. It seemed as though the clunkyness of paging someone was a feature so that doctors on call were actually getting relevant information.

      Some telcos are willing to guarantee that pager messages will arrive. No-one’s willing to guarantee shit for mobile phones.

        The one I worked at was a very large modern university hospital (in the US) that handled a large part of the states patients. We used pagers in the Emergency Room for code red patients. Many doctors also still use them

    Mirrors on cars.

    I mean, logically I know why, but it just feels so weird and out of place in the 21st century.

    Like you got this high tech vehicle with a bunch of computers inside and a lot of screens/displays, radios, GPS, “assisted driving”, then you see this mirror that’s thousands of years old and not some advanced 360 radar system.

    I know that a mirror isn’t gonna fail like electronics do, so its better reliability, but still feel odd seeing old tech and new tech merged.
