Whether big or small. We all have that one thing from Scifi we wished were real. I'd love to see a cool underground city with like a SkyDome or a space hotel for instance.

I would just like complete control of my various web things. be able to restrict banking activity by source (so like lock my savings to only move between my checking and no where else), be able to make temporary credit card numbers that I can not only limit the amount of a single charge but max total that can be charged and daily charge and monthly charge and also be able to limit it to one payer. So like I make it and use it to pay for something than can go back and click on the the vendor payed and say lock it to only that vendor. Have an investment account where I can setup a variety of investments by percentage and have it keep those percentages as markets move. oh and have a local location for all my things where you can get any help including for their website although thats not exactly technology.

AR. Being able to just pop into someone's AR world and walk around as if I was in tge same physical location.

Bikes/Ebikes/motorcycles replacing cars for single-person transport in cities.

VR chat.

AR is more complicated.

[–] Alcoholicorn@mander.xyz 1 points 2 days ago

Yes, I want to pop into a live recreation of the world around somebody (as a sparkly wolf dragon with a 3million polygon ass obviously). We have the technology, just not the hardware and software.

Brain operated electronics.

Eeg headbands detect brainwaves and are used in diagnosing mental illnesses. There is also expensive portable ones for yoga people that track your sleep cycle and give statistics.

You can VERY easily have it change the TV channel or move player in a VR game. In fact there is an old starwars toy where you lift some ball by powering a hairdryer with your brainwaves for like $40.

How about a machine that can fold your laundry after it's washed and dried?

Mech suits.

We have them IRL... Kinda. They're just hydraulic powered limb-augmentation things but there's absolutely no reason they couldn't be like an Alice from Aliens. Shit; we could probably do MechWarrior mechs just not the same scale right now, or even an Iron Man like suit if time was spent trying.

The most fictional thing about a lot of these is mostly the power source. How do you power it? But a tank with legs could just be powered by a normal engine.

Medical Biofoam from halo, we have prototypes already

[–] tal@lemmy.today 27 points 4 days ago (10 children)

I'm confident that we could set up permanent human habitation on the Moon or on Mars with our current level of technology, and that's featured pretty prominently in sci-fi.

I don't know if it would actually provide a cost-effective return, but I do think that it'd be interesting to see happen in my lifetime.

Finding a way to use organic matter in 3d printing so I can say "Computer...one strawberry milkshake", similar to Picard.

Fusion energy. Man, we are so close!

[–] DasFaultier@sh.itjust.works 32 points 4 days ago (1 children)

Yeah, you know what they say: only thirty more years.

[–] darkdemize@sh.itjust.works 20 points 4 days ago

With adequate funding. That's the part that always gets omitted. We haven't been funding the research to make it happen.

Alarm clock that reads my brain activity and only wakes me up at the point in my REM cycle, where i'll feel refreshed waking up.

Just a few more billions and it'll be complete.

Terraforming.

The formerly-water deserts can be terraformed by just digging holes at specific angles so the shadow protects plants from drying up.

It's sci-fi not like a "future robot" thing but more of a "hey we know the math we can do this reliably well" type of thing.

Also those expensive EEG headbands that track your brain during sleep and give you stats can be modified to change TV channel at specific brainwave values.

[–] L0rdMathias@sh.itjust.works 21 points 3 days ago (1 children)

I've got good news for you! We've been terraforming the planet to be more like Arrakis for a couple decades already!

[–] silasmariner@programming.dev 2 points 2 days ago

Ah, the chapterhouse: Dune strategy
