    A full working computer, more powerful than what we used to go to the moon, and using less power than a light bulb.

    It can take many forms, like smartphones, SBCs or older PCs/laptops.

      You can buy an ESP board that meets all those qualifications from AliExpress for less than $3CAD shipped.

      Setting one of those up was the first time in a while I’ve been so impressed with just how cheap and accessible tech has gotten. It’s a web server with WiFi and Bluetooth shipped to my door all for the price of a chocolate bar.

      By that logic, a lighter. Better than smashing two rocks together, that’s how we used to make fire.

        One of those fancy plasma lighters, sure. But butane lighters have been around for decades

    Raspberry Pis and other microcomputers can be had for pretty cheap, and they can be put to a surprising variety of tasks. You need to be a bit of a jack of all trades to fully embrace that DIY element, but I’d bet that showing off a project that you mostly built yourself would be seen as futuristic by most people.

      The RPI400 is basically a full solution. You just need a display and a mouse, and you have a fully functional desktop computer. Not very powerful, but good enough for basic tasks like writing documents or browsing the web, coding etc.

        The tape head is basically a small and really sensitive electromagnet. Magnetized tape creates small disturbances in the magnetic signal. Amplify those disturbances and you get sound. Similar to an antenna, but only works in close proximity.

        This also works in reverse. Feed an audio signal through the electromagnet, and the electromagnet will create the disturbances in whatever is next to it. You can do this to record to a tape, or you can do this to pass sound to another tape head, which is how these aux cassettes work.

        You can build one yourself really easily. Just take the tape head from a broken player and solder to an aux cable. Take a cassette, remove the tape, and put the tape head in the middle portion so it comes into contact with the player tape head.

          Of course it’s Technology Connections. Who else would make a video about a (now) useless piece of 80’s tech with enough content to satisfy any level of curiosity.

    Devices less sophisticated than smart phones were once pretty common in sci-fi novels, but they still achieved the same sort of thing, all the world’s knowledge in the palm of your hand.

    You can get smartphones for absurdly cheap these days, and while crappy by modern standards they’re still technological marvels.

    A knife. Futuristic in that it will be handy for hunting and self-defense after the future collapse of civilization that results from our insatiable appetite for consumption - of, among other things, useless gadgets.

      It’s interesting the difference in what people think a collapsed civilization will look like.

      Some people think we will “return to monke” where wilderness survival skills will be essential and people who have them will be the “main characters.” That would probably be the easier and better future.

      The more likely option will be technofeudalism where rich people have small, brutal armies and control localized power grids, farming operations, and politics with tech as mass migrations happen and wildlife becomes all but extinct outside of human cultivation. Survival skills won’t matter when all land and food scarcity is controlled by a rich few with absolute control. The average survivalist will be wiped out with the first natural disaster or by the feudal lords with drones. Return to nature might only come after 50 years when chip supplies and power grids have dried up and fallen apart, but it would just as likely be mad-max as oil could likely still be used.

      Who knows. Fascism might take over with how it is going now and solve the climate crisis with mass genocide and forcing green energy for all we know.

        I see you’ve read Yanis Varoufakis. In all realism though, a fallen society is most likely to be a result of climate change. First it gets too hot for Africans, so their only option is to move northward and eastward to the Middle East. This results in tightened borders and the death of many due to heatstroke and dehydration - I also don’t doubt a slave trade-like and human exploitation era might come about because of this. Increased demand for AC’s in the west will also be a byproduct of this. Melting ice caps will also increase the danger to many of those living in coastal regions - Florida probably sinks faster than we’d predicted.

        All of this I project to happen within the next 50 years where the problems are left for Gen Z and further generations to deal with.

          It’s more or less an inevitability at this point, regardless of what we do. Really we’re just trying to get corporations and countries to make changes so it will be Gen A’s (or the following generation’s) problem instead of Z.

          Normalcy now has an unavoidable term limit. The question is if we’re going to shorten how long that timespan is by desperately holding onto normalcy now for as long as we can, or if we’re going to start making things harder, more challenging, and less normal sooner to make the transition less painful and give it a longer on-ramp.

          Currently we seem to be choosing option A.

          For what it’s worth, I’ve seen some friends take things a little more seriously when I’ve explained that currently we’re going to see abrupt and incredibly disruptive changes at the point in our (Gen Z and Millenials) lives when we’re at the age when we’ll be least able to tolerate the changes and most reliant on others. In 40-50 years, Z and M are going to be senior citizens at best. While we may be full of distracted, dopamine-seeking denial now, by the time shit really starts hitting the fan, we’re going to be extra weight on the generations struggling desperately to survive.

          Don’t expect a happy retirement.

    If you shop around you can find a Brother (B&W) laser printer for about $100.

    Imagine this weird future: Printers that always just work no matter what type of computer you have or how long they’ve sat since you last used them. And the “ink” cartridges last forever. And you can buy 3rd party refills or even refill them yourself. Plus it’s completely reliant on microplastics to do its job, what’s more futuristic than that?

      I’ve got one of those and I’m pretty sure I’ve been using the same toner cartridge for like a dozen years.

      I lived in the 90’s, when office work was a tad more reliant on printers and late stage capitalism wasn’t as bad. My dad had a laser printer for his business. Very reliable, fast, never needed anything.

      I remember that as the past, is my point.

        I was thinking this too, but consider some improvements:

        • wireless printing seems to “just work” now. Besides having to painfully enter my wifi password with up and down arrows on my printer, it seems like my windows and Mac laptops are able to print to it wirelessly without any initial setup. (I use Linux on my desktop but haven’t tried printing from it yet). I think it even works from phones.
        • cables: I don’t remember what type of cable printers used, but I remember the big keyboard cable, then the smaller purple and green PS/2 ones (I think keyboard and mouse were different?)… I vaguely remember multiple different peripheral cables, like FireWire? Giant parallel ports for things like scanners?

        I hate that most printers don’t come with the USB (B?) cable that seemingly only printers need now, but I’m glad that it’s standard and that everything supports <strikethrough>USB-A</strikethrough> I mean USB-C (except my PC) now. Such a utopia.

      Even better, if you scour your local thrift stores you can occasionally find them for as little as $10 and all they typically need is a cleanup and a new toner cartridge.

      I bought mine for $7 4 years ago and it’s still working on the toner cartridge that was in the printer when I bought it.

      Admittedly, I only print about 40 or 50 pages a year but that’s a hell of a deal.
