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.)

Sex robots!

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.

Flying taxis won't happen, way too many risks, even in the future, never mind the horrors of having your skies full of that crap.

We have auto-pilots for planes, those are mostly fine. People are the problem. I dont trust humans to operate motor vehicles in 2 dimensions, let alone 3...

[-] [email protected] 1 points 1 hour ago

I don't think auto pilot works how you seem to think it does...

[-] [email protected] 1 points 50 minutes ago

Obviously I know how they work, I saw it in a documentary about Airplanes. The Otto pilot inflates at the press of a button (or is inflated manually) and they fly the plane.

A lot of black mirror stuff.

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

[-] [email protected] 4 points 7 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.

I've seen prototypes of these that were very impressive since like a decade ago, so I'm fully expecting those to be here soon. Power supply usually is the biggest issue

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

[-] [email protected] 1 points 3 hours ago

I saw something about a city in India being super eco-friendly. I'm not sure what was the name of the city, but it looks like they have a few.

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

[-] [email protected] 8 points 1 day ago

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

[-] [email protected] 6 points 22 hours ago

I thought we already had rail guns on ships?

[-] [email protected] 3 points 5 hours 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.

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.

[-] [email protected] 18 points 1 day ago

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

[-] [email protected] 12 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!

[-] [email protected] 2 points 5 hours ago

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

I'd just sit in the shade.

[-] [email protected] 2 points 16 hours ago

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

external gestation...a womb with a view

severe genetic manipulation... designer babies

They just released a story about removing the gene that causes down syndrome. Pretty huge

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

[-] [email protected] 2 points 16 hours ago

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.

[-] [email protected] 1 points 13 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.
