What's a sci-fi thing you feel is achievable with our current level of technology that you'd love to see become a thing?

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.

  • 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.

    • I'm an engineer in R&D and have briefly worked on an exoskeleton project. The reason we don't have mech suits is that the capitalist market doesn't demand them much, at least with our current technology.

      There are two primary markets for them: medical, and manufacturing. I worked on the medical side--the big challenge there is making devices that are light enough that the mech helps more than it hinders. The biggest challenge is power: batteries are heavy. As we continue to figure out more efficient power storage and efficiency techniques, you could see more of these devices out in the wild.

      The manufacturing market is growing, though most applications there are less "mech suit" and more "assistive arm" type of things.

    • So you want wanzers.

      Seriously though, realize that if we ger Mecha, it's going to be more like Armored Core. Or a game set in an AC4 AU, Metal Wolf Chaos.

      Do you want the US President (especially the current one, to have something like that, and be told to believe in his own justice?

      • We already know what a president with a robot body is like.

      • IDK why they would need to be that big. I don't even think physics would allow them to be that big. The scale of these things in fiction is pretty absurd. Especially the big walker boss in AC6. Your AC is already like 4 stories tall, and that thing makes you look like an ant.

  • Nuclear rocket engines. A bit less ambitious than most of the responses, but most things here seem to either refer to technologies we don't have yet but seem within a century or so of developing, which doesn't fit the question, or vague consequences that one wants that tech to have without it being clear how our current technology gets there. But nuclear rockets definitely fit the question, because we have built and ground tested them before, decades ago even, we just haven't bothered to actually use the things. And they should theoretically make developing things like space industry or manned space exploration beyond the moon more viable, by being more efficient than chemical rockets while giving better thrust than ion engines do. They don't work well for launching from the ground, but since our launch abilities have increased a fair bit in the past decade or so, actually getting the things to space in order to use them should be easier than ever.

  • Downloadable internet. You stick a pendrive in your PC with internet connection, fill it with internet and then go wherever you want, you have a usb router with data available to use and surf the net.
