Pager and satellite phone. Mostly a niche usecase for health workers and remote location settlement respectively.
Pagers.
Still in use by hospitals and emergency services
Shit works
General Aviation is still using magnetos. The typical GA airplane is hilariously primitive.
NOOO I NEED LEADED FUEL CAUSE MY LYCOMING IS FROM THE 60s 😭😭
If you buy a brand new Skyhawk here in the space year 2025, it will come with a newly made Lycoming IO-360 that requires 100LL. I think they’re still working on eliminating leaded avgas, I think because the Trump regime hasn’t noticed it yet.
The IRS still use COBOL.
So does pretty much the whole banking and credit industry. When you get money out of an ATM there’s usually some COBOL code involved.
True, we stack old technologies on top of older technologies, and somewhere at the bottom, there is z/OS with COBOL running. A young person right now learning COBOL has a secure future with big paychecks.
Depends on your tolerance for code spelunking. Back in the 90s I was encouraged to do Y2K prep because I had some COBOL experience, but I really hated pawing through old code. To be fair, COBOL was designed to be self documenting and English-like. But I’m glad I got into web dev instead back then. It was right at the dawn of “dynamic HTML” when web pages started actually doing things. Very cool time. Right now I’d be more inclined to go into helping companies recover from failed AI projects.
That’s not even a government thing. It’s a finance/banking thing, as most major banks are still using mainframes and legacy COBOL code for most of their business logic.
Reminds me I have to catalogue 2 Tandem Non-stop! Systems at work… I don’t need to meddle with the cobol code atop but still, this was quite a surprise to stumble upon.
Steam engines.
The vast majority of our power comes from making something really hot and boiling water. Coal plant? Oil plant? Gas plant? Nuclear fission plant? Geothermal plant? The grand holy grail of energy production that would be a nuclear fusion plant? All steam engines.
Yes, unbeknownst to everyone, this is what a steampunk society realistically looks like.
After first contact
A: These are our mini neutron star fusion reactors. The most advanced technology to have ever existed. We basically take a chunk of neutron star matter and divide it into two. We neutralize the negative effect and extreme gravity with our space-time bending gravity manipulation technology. We let the two mini neutro spheres accelerate and collide. This generates enough energy to power atleast 3 planets for 1000 cycles. Not onl–

Stolen from reddit.
We made steampunk a reality by developing the technology to transfer steam power efficiently over long distances through metal wires.
Trigonometry is still used to take measures all around the world.
Welcome to “That’s not surprising at all!”
Fax, still in official use in Germany.
It’s considered a secure method of document transfer over email, despite email being able to be secured and fax can be hacked with like a length of wire and a knife. Fucking irks me.
How does one hack fax in that fashion?
Fax operates as data over phone line, similar to dialup. If you can get a wiretap on a phone line, you essentially can get everything that passes over it. Technically you could encrypt it, but it’s usually not required you do legally.
Very common in the US medical field as well
Fax is too simple to completely die.
I’m surprised nobody mentioned jack plugs yet. Basically unchanged since 1877 when it was invented for phone switchboards, roughly as old as safety pins or modern hairpins (give or take a few decades)
If it ain’t broke don’t fix it.
That can’t be the actual name of those, is it?
I’ve always kinda wondered, and generally call them TRS or something (I’m audio engineering background, American, millennial), so looked it up:
From https://en.m.wikipedia.org/wiki/Phone_connector_(audio) under the “other terms” section:
The 1902 International Library of Technology simply uses jack for the female and plug for the male connector.[3] The 1989 Sound Reinforcement Handbook uses phone jack for the female and phone plug for the male connector.[4] Robert McLeish, who worked at the BBC, uses jack or jack socket for the female and jack plug for the male connector in his 2005 book Radio Production.[5] The American Society of Mechanical Engineers, as of 2007, says the more fixed electrical connector is the jack, while the less fixed connector is the plug, without regard to the gender of the connector contacts.[6] The Institute of Electrical and Electronics Engineers in 1975 also made a standard that was withdrawn in 1997.[7]
The intended application for a phone connector has also resulted in names such as audio jack, headphone jack, stereo plug, microphone jack, aux input, etc. Among audio engineers, the connector may often simply be called a quarter-inch to distinguish it from XLR, another frequently used audio connector. These naming variations are also used for the 3.5 mm connectors, which have been called mini-phone, mini-stereo, mini jack, etc.
RCA connectors are differently shaped, but confusingly are similarly named as phono plugs and phono jacks (or in the UK, phono sockets). 3.5 mm connectors are sometimes—counter to the connector manufacturers’ nomenclature[8]—referred to as mini phonos.[9]
Confusion also arises because phone jack and phone plug may sometimes refer to the RJ11 and various older telephone sockets and plugs that connect wired telephones to wall outlets.
fax machines, both in Germany and Japan.
They’re common in the US too in doctors offices and hospitals because of the security requirements of transmitting patient records and such.
I used to work at a retail store not even ten years ago, and we would submit delivery orders via fax. It’s weird until you realize they’re great for reliability and record-keeping. No batteries needed, totally existing infrastructure, kinda fun to use tbh.
As someone who directly manages faxing in the company i work for, yup! In Healthcare and we send out results to doctors and hospitals through faxing all day every day. We have mostly converted to electronic fax. We still control the servers on prem but the account is linked to a cloud solution so all the faxes are created with the servers and instead of using our own telephony solution like we used to, we send directly over internet to the provider who then sends out to the clients at the last leg. Hundreds of thousands of pages every month. From my understanding, it’s still the easiest solution to get away with not having to implement some new system that will be subjected to audits. Faxes are accepted, and little is required to show for compliance.
Interesting, how is eFax any more secure than email? The advantage of fax is it’s one machine to one machine, no possibility of interception without physically tapping the POTS line.
It’s not. Information is secure at rest and encrypted during transfer, but once it reaches the part where it is sent over voip using a telecom provider, it has the same issues as it always did. We use it because its the best way to send this many faxes, as well as automate things using our internal applications to send faxes through it as well as other applications that we leverage its API to use the service. One advantage that makes it semi more secure is if we send a fax to another client that also uses the same service as we are then then it’s actually a secure stream for the entire path.
And it’s WAY older than people think. The first patent for a fax like machine was granted in 1843.
Microsoft Windows
If some of the stories are to be believed, some of the code dates back to 3.1/dos too
Oh you can clearly see that this is true when you launch certain programs:
https://www.reddit.com/r/Windows10/comments/o1x183/the_famous_windows_31_dialogue_is_again_in/
Oh that’s tremendous, I don’t run windows to see this. But come to think of it I have come across some ancient screens doing odbc/data connections ancient popups in excel at work!
UNIX
The sewing machine. Like we got 3d printers than can give me whatever I want in 20 hrs but I still got to fight with a sewing machine to stitch an outfit. Like why no polyester clothes printer?
For one, polyester fabric and clothes are just terrible
Two, technically you can 3d print a chainmail shirt, but it’d suck to wear normally
We have knitting machines, and automated looms (weaving machines,) we even have sergers for fancy sewing. Its just plain easier to make the finished product as a custom job since humans aren’t uniform in size, and it’s way easier to weave a rectangular piece of cloth than any other shape.
IPv4.
IPv6 became a recognized standard by 1998.
EDIT: https://www.google.com/intl/en/ipv6/statistics.html#tab=ipv6-adoption
Nearly 30 years later, and less than half of the connections to Google are via IPv6.
IPv6 is such an ugly monster.
It just isn’t and I’m sick of people being scared of hexadecimals lol
You can even spell stuff with them which is way easier to remember, my router’s ULA is fd13:dead:beef::1
Fucking NAT. Never should have been allowed to escape from the lab.
Lolol, you’re not wrong. NAT made IPv6 a later problem
I ❤️ IPv4
There’s no place like 127.0.0.1
There’s no place like
::1I can’t understand that gibberish, speak RFC 791 like a true patriot
Based on how ISPs seem to not get their CGNAT setups right, it’s not going away any time soon.
As a South African, I have never even seen IPv6. My university has two /16 blocks and no NATing
I’m almost at the point where all of my connections are IPv6, but still hampered by my mobile provider (ironically, since IPv6 was generally adopted earlier on mobile in many countries).
Steam turbines.
Like those damn nuclear reactors!

Really depends on the place. Most chain stores, restaurants, etc, will have tap to pay. It’s mostly local businesses using old hardware from budget credit card merchants that really require you to sign anymore. Sometimes there’s the odd tap and still have to sign, but it’s usually done on the electronic pad.
