3D printing.
I’ve had a 3d printer for years and I still can’t really get over how nuts it is. Like it feels like one of those things you’d read about in science magazines as this amazing super scientific thing the scientists out in MIT have in their labs like a supercomputer or some expensive toy people who build stuff on YouTube have in their garage next to the lathe and big fancy CNC table, but no, it’s just, here. On my desk. Being used to casually print stuff that I’ve designed myself on the computer like it’s nothing.
My great grandad was a carpenter and I wish I could’ve shown him it. I wonder what he’d think, seeing something that was once only in the realm of handcrafted diagrammes and days of building now a few hours of modelling and printing away.

The technology behind it isn’t new, but The Thought Emporium is a Youtuber who:
1: DIY-d a genetically modified virus to cure his own lactose intolerance (successfully)
2: Is currently working on a biological computer that runs on animal neurons.
3: Has livestreams where the viewers submit ideas (like making tomatoes spicy) and he designs DNA to accomplish it.
Also he helped shut down a scam health product that contained radioactive material which isn’t particularly futuristic (actually it reminds me of the “radiation is good for you” craze in the early 20th century) but I wanted to mention it anyways.
We have phones as powerful as computers in our hands when 20 years ago that was impossible. The exponential growth of computers and smartphones is mind-blowing. And the amount of technology that has bloomed from all of that
Lithium polymer batteries that make advanced computing portable. We wouldn’t be able to create multi function cell phones without the battery power and longevity of those batteries. Star trek tricorders are going to be the next big tech coming to the generation after Gen z.
Yes, I love carrying potentially explosive batteries in the pocket…
I hope you also love driving an actual explosion. Also known as a car.
I wish you people would actually do a comparison between ICE engine explosions vs. EV explosions.
Guess what? Firefighters can actually put out ICE vehicles, but they still haven’t figured out a solid way of putting out EV batteries.
Guess what? When ICE vehicles explode, more often than not they’re already running and there’s some electrical short or something. EV will just as soon explode in your garage while you’re sleeping.
Guess what? Studies show that since EV’s are way heavier, they wear through tires way faster? Did you know it takes approximately one barrel of crude oil to make an average car tire?
Guess what? Autonomous vehicles seem to have a habit of getting confused around emergency vehicles and causing wrecks, into the very vehicles meant to save people from accidents.
Guess what? Lithium ion batteries are typically rated for a max safe temperature of around 40⁰C, while the pavement the battery sits right over can be over 80⁰C
I’m too lazy to look up links, you’re smart, go Google these things or whatever. All these facts check out.

Guess what? You’re wrong on all points. Studies show that you have 5G Corona and should report to Bill Gates immediately.
Also, I actually had a vehicle from 1987 that totally flooded the cylinders with gasoline due to a fault in the carburetor, and even then it didn’t explode when I started it.
Seriously though, what’s up with these EV’s that’ll just as soon randomly burn your garage and house down while you’re asleep and the car isn’t even running?
Liquid gasoline is not what will explode. You need vapors. Gasoline still requires oxygen to burn, so if air is not mixing with the fuel, nothing’s gonna happen.
An internal combustion engine relies on having an environment of maximum flammability in order to function correctly. It’s when that environment is no longer contained by the engine that you run into catastrophic problems. Multiplied by how empty your fuel tank is.
This is quite true.
Still, gasoline doesn’t have a tendency to up and spontaneously combust all on its own, it takes some sort of external spark or flame to ignite.
Lithium batteries play a different game of Russian Roulette though. The car doesn’t even have to be running for one worn out cell to overheat and cause a catastrophic chain reaction blowing the entire battery pack.

I don’t mean to sound ungrateful, but wake me up when we’ve got replicators and holodecks. They’re as enticing now as they were decades ago.
If you lived in a society that had ready access to replicators and holodecks, you’d probably be asking for teleportation and eternal youth.
What’s amazing yesterday is boring today. That’s kinda part of the human condition.
Being able to fly anywhere in the world with almost zero planning, and then being able to communicate back to anyone at home with almost zero delay, would have been unheard of just two generations ago, but now that it’s normal, it’s a shrug and look for the next thing.
If you’ve got replicators, you already have half of a teleporter, and you already have the technology necessary to fabricate replacements for failing body parts, so you’re already at least partway to teleportation and eternal youth.
Tricorders are 70ies tech. 2000s dumbphones are more advanced.
You’re thinking of their com badge, the tricorder was the thing they flipped open to analyse a rock or reverse the polarity of a time crystal. It could do basic medical work, interface with electronics, detect life forms, determine if plants are edible, all sorts
Oh. Yup, my bad.
The air fryer is pretty cool I guess.
Voyager 2
Blows my mind every fucking time I read about it.
Props to the USA/NASA and their engineers for achieving something so long lasting with technology from ~50 years ago.
Data compression. Something about “making less data out of … The same data” is really mind blowing, & the math is sick
It is not that complicated, to make a simple example with strings: AAAABBBABABAB takes up 13 spaces, but write (compress) it like 4A3B3AB take up 6 spaces compressing it more than 50%.
Now double it like AAAABBBABABABAAAABBBABABAB with 26 spaces and write it as 2(4A3B3AB) with 9 spaces it takes only 30% of the space.
Compression algorithms just look for those repetitive spaces.
Takes those letters and imagine them being colored pixels of a picture to compress a picture
Once you get into audio, images and video it revolves a lot around converting temporal and/or positional data into the frequency domain rather than simple token replacement.

Don’t overthink my example, it was just a representation

I’m holding a small device in my hand that gives me access to all of humanity’s knowledge.
Granted, I’m using it to dick around on Lemmy, but…
To be fair there’s plenty of knowledge on Lemmy as of today… And porn, lots of porn.
The Internet is for porn!
I have yet to encounter any porn on lemmy.
Do you have the NSFW filter off within your Lemmy or app’s settings?
On behalf of Gnorv, yes. I have made sure multiple times that my NSFW filter is off. I have only seen an occasional NSFW - like One per month, and it’s never porn - even when I browse by New.
Please Help.
If you go to the instances page of your lemmy instance (eg lemmy.ml/instances) you can scroll down to the “Blocked Instances” section and you’ll probably find the bigger nsfw instances are blocked.
You’re not trying hard enough 🤪
Being trans always was such a cyberpunk concept to me. When I was a kid was like “people can change their gender? Cool”
We can say that… it was a sign lol.
When I was a kid there was only one openly trans person I would ever see. A man at the library who wore women’s clothes (to put it in the terms we would have used then). They didn’t try to be feminine beyond the clothing. Very occasionally some makeup. Legs were not shaved etc.
I was at the library on a weekly basis and saw this person all the time but it was just this one person. My mother told me not to stare or make fun of them and that they weren’t hurting anyone and could dress how the pleased.
Now, some forty or more years later I frequently encounter non-binary people, trans people, etc. I follow the same method my mother taught me. They are just people living how they want.
It is interesting to be that William Gibson had trans characters in Johnny Mnemonic, for example, written in 1981. That’s around when I would see that person at the library.
Modern cell phones. It’s crazy that I basically never need a computer now. My phone is so diversely useful. I spend more money on phones than computers now. It’s also the best camera I’ve ever had! Phones are just so cool lol.
I know where you are coming from, but I can’t see how a phone would be a replacement of a computer, not with Android nor iOS, maybe we need a better mobile OS 😂
My Mac is on repair currently and one of my most uses for it was to manage my docker containers hosted in my NAS, while I can do some of that in my Android phone it is a pain in the ass to work with it, especially if it can retain many tabs opener as any modern browser lol.
The Samsung Dex thingy kinda gets close to this new future though.
I feel like the average person doesn’t need a computer most of the time. Anyone who’s a “power user”, for lack of a better term, probably does. I run a VM with a desktop OS on my Proxmox setup that I remote into from my phone for things that I require a full OS for but don’t want to break out my laptop. I often find myself remoting into it from my laptop anyway just for continuity.
We also need physical keyboards on phones. I want my Droid 3 back.

We have Mustard flavored Skittles now.
Truly we’re on the last frontier.
I walk into my house and start dictating to a speaker sphere what lights to turn on, what to set the thermostat to, and to turn on the tv. And she answers. Just like in sci fi movies.
It’s all fun and games until she creates herself a Life-Model Decoy and traps you inside the house in order to “protect” you.
Oh yeah, I forgot that that used to be a sci-fi thing, but it definitely was when I was a kid.
