Sex robots!

Most of the stuff in Jules Verne's books, even Paris in the Twentieth Century.

(Well, the moon gun would need to be a very long railgun, not a gunpowder cannon, if you want crewed capsules, but still.)

[–] DJKJuicy@sh.itjust.works 1 points 1 hour ago

I'd really like to at least see humanity fully switch to clean energy in my lifetime but I'm losing hope.

I should already be able to take a self-driving flying taxi to work. I should already be able to vacation on the moon. We shouldn't be burning stuff to power all our modern tech.

I grew up on 80s/90s scifi. I hope humanity can get it's shit together and that the current anti-intellectualism phase we're in is just part of a larger cycle.

[–] GrayBackgroundMusic@lemm.ee 2 points 2 hours ago

Exoskeletons like Ripley's in Alien. We've got smaller ones, but I want to pilot a walking fork lift.

Pipe dream - battlemechs aka mechwarrior (not pacific rim). Very impractical but I want one anyway. Yes, I saw the robot fighting league by Megabots. I have their poster.

[–] Strider@lemmy.world 5 points 3 hours ago* (last edited 3 hours ago)

A lot of black mirror stuff.

Apologies for the blanket pessimism but the last decades darkened my view.

[–] match@pawb.social 7 points 12 hours ago

living in a self-sustaining ecological-aware community that values freedom and diversity and everyone having their needs met

[–] londos@lemmy.world 22 points 23 hours ago

Vaccines. Maybe in 100 years we'll even be able to eliminate measles...again.

[–] Toes@ani.social 7 points 22 hours ago (1 children)

Railguns, there already exist prototypes that destroy themselves. So close!

[–] surewhynotlem@lemmy.world 6 points 18 hours ago (1 children)

I thought we already had rail guns on ships?

[–] scintilla@lemmy.blahaj.zone 2 points 1 hour ago

No. Well kinda.

The Ford class uses what is basically a rail gun to launch planes but big navy decided against continuing development on railguns as a weapon.

[–] acockworkorange@mander.xyz 7 points 1 day ago

We currently carry tricorders in our pockets. I can see a medical tricorder being ubiquitous for field medics, ships, and the like within 100 years.

[–] whotookkarl@lemmy.world 14 points 1 day ago (3 children)

Tricorders, cellphones are already partway there they just need more durable, small sensors like a handheld light spectrometer to tell what things are made of and a handheld interferometer to detect gravity

[–] invertedspear@lemmy.zip 10 points 1 day ago

Check out the app Phyphox, it uses all your existing sensors and probably surpasses tricorders in several ways while, of course, lacking in a few others.

Fast-refresh ePaper. I just want a laptop I can use outside, man!

[–] Blackmist@feddit.uk 1 points 48 minutes ago

They exist as monitors. In videos they kind of look like really early crappy LCD screens.

I'd just sit in the shade.

[–] BackgrndNoize@lemmy.world 5 points 2 hours ago (1 children)

Look up Daylight DC-1 might be what you are looking for

[–] Distractor@lemm.ee 2 points 1 hour ago

Oooohhh, thank you

[–] hanabatake@lemmy.ml 1 points 12 hours ago

I remember we could use the game boy advance SP outside. Is this screen technology used for PC?

[–] Dagwood222@lemm.ee 3 points 23 hours ago (1 children)

Asteroid mining. We've had the tech to get people to the asterodi for decades, just lack the will to do it.

[–] Fleur_@aussie.zone 2 points 12 hours ago (2 children)

Okay I've had this astroid mining concept dining around my empty skull for a while now. The way I see it is that going up to space and mining an astroid for minerals and then bringing them back down to earth will never be a worthwhile endeavour. If you're mining them in space and using the material manufacturing in space then that seems more plausible. The only way I can think of planetary based astroid mining being worthwhile is if instead of mining the rock and sending it down in crafts, you just bump the astroid so it's on a collision course with earth and then mine whatever is left from impact. In anycase, I'd say we are far off being able to mine asteroids since imo, the only worthwhile way to do it is by having the entire process in space. And we're not even close to that level of infrastructure existing in space.

Here's a link to some books on the subject. You're right, most people figure it would be putting our heavy industries in space and bring down what ever products are needed.

[–] Kyuuketsuki@lemmy.ml 1 points 8 hours ago

We can get a major shot in the arm if we can find a solid industrial use for iridium that sufficiently eclipses any other element. Or some alloy to the same effect.

Unfortunately, it's so rare that it's next to impossible to do any real amount of testing.

Suicide Machines on Street Corners.

[–] hungryphrog@lemmy.blahaj.zone 1 points 1 hour ago (1 children)

That'd be pretty expensive to run if you think anout it. And who'd do the cleanup?

[–] Blackmist@feddit.uk 1 points 47 minutes ago

Blend them up and flush them into the sewage system.

[–] BackgrndNoize@lemmy.world 1 points 2 hours ago

I read that as Sucide Marines and was confused for a bit

[–] barneypiccolo@lemm.ee 3 points 23 hours ago* (last edited 23 hours ago) (1 children)

They already have them that you can carry in your pocket.

[–] sulgoth@lemmy.world 2 points 13 hours ago

Yeah but they make such a mess.

[–] Lasherz12@lemmy.world 25 points 1 day ago (1 children)

Artificial stem cells seem like the next thing to really revolutionize medicine.

Quantum computers for brute force hacks seems doable in 100.

Eye tracking pointer devices will likely be more convenient than mice within a dozen or two years. This will probably be widely available for people who are paralyzed first.

Diamond processors are always 10 years away, but I think we can do it in 100. This would revolutionize the amount of power we can put through a chip without worrying about cooling.

Quick charge capacitor replacements for standard rechargble batteries

Low yield fusion plants. I'd like to think of them as capable of high yield, but it's much harder than initially thought. Some ideas are quite promising for low yield.

[–] Lizardking13@lemmy.world 3 points 23 hours ago (1 children)

The eye tracking stuff exists already. There are medical device companies that build and sell these things.

[–] Fleur_@aussie.zone 2 points 12 hours ago (1 children)

I feel like the bottleneck will be with smooth continuous motions. It's very easy to move a cursor in that way with a mouse but you can't do that motion with your eyes unless you are looking at something else that's moving.

[–] Lizardking13@lemmy.world 1 points 1 hour ago

Fair. Check this out. The existing stuff is pretty cool https://youtu.be/CP3t8qMHcsM

[–] Justdaveisfine@midwest.social 20 points 1 day ago (3 children)

I suspect we will see a human brain to digital interface. I don't think it will be "downloading minds" or anything, but I could see someone finding a way to plug a specialized camera or mic in to have a full functioning robotic replacement part.

I'm pretty sure they already have the beginning pieces to this, but its too specialized and expensive to do anything commercial with it yet.

[–] pleasestopasking@reddthat.com 3 points 14 hours ago (1 children)

This is so terrifying to me. I feel like it'll end up like the Black Mirror episode with the subscription model, getting more and more expensive with fewer features.

[–] WindyRebel@lemmy.world 1 points 6 hours ago

Common People

That episode made my wife and I really hope this tech never becomes a thing.
