    From what I've seen about a space elevator, is that the we don't have the means to do it without creating a massive material shortage in the world.

    The most plausible idea I've seen is using the centrifugal force of the earth spinning to keep a mass at LEO. But without a futuristic material like long carbon nanotubes, we would have essentially a ten mile thick metal cord tapering to something a few feet thick, and you would be limited in payload to like a few hundred pounds.

    Just curious, why do you think a ring would predate the elevator?

    (Not OP) Because simply from a construction-point-of-view it's achievable now. Unlike a space elevator, a ring could actually be built and used with today's materials.

      Maybe I'm just a pessimist, but I don't see us launching enough space raw material from ground level to build it. Not trying to sound rude, I've just been in the logistics game(even helped put a small satellite into orbit) and I just don't see the millions of tons of material needed being launched from the ground. Again, not trying to sound rude, this is just my observation from being "in the game".

          Constructing an Orbital ring and then using that to get a form of space elevator built.

          Totally possible to build with our current technology but the cost if we do it pre space elevator or similar is pretty insane.

          Building a ring let's us basically have a stable space side anchor at low earth orbit instead of geo sync ish like you need for a normal space elevator to match ground speed.

          Even more fun is cost for additional rings drops massively and you can build them in different orientations you can get space elevators to rings without having to be on the equator.

          https://www.youtube.com/watch?v=LMbI6sk-62E

          Last and my favorite part is the possibility of having literally trains that go up to a ring cross an ocean and go back down. Wouldn't be faster than planes but massively better cargo capacity and efficiency as well as comfortable for passengers.

            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.

            It is funny because that defeats the principle of the Internet as a shared, live, always on always available data space 😄

                Arcologies.

                Dense housing with good soundproofing, atop commercial space, in a walkable neighborhood.

                Wouldn't need rent control if there was more houses.

                  I'm going to go against the trend here and say that libertarian corporate city-states actually sound pretty cool. They're generally not portrayed positively in fiction but I think they might work well in practice. I'm a lot less optimistic about cooperating with all my fellow Americans in order to govern the whole country democratically than I used to be. Choosing to move to an independent city-state with a government that I agree with (albeit one I don't elect) might work better.

                    First explain to me what technological limits are creating the food scarcity we're experiencing.

                    Sounds to me like you don't understand the question.

                    The food scarcity is certainly not due to technological limitations, but we very much can't create food for free. The food you eat is produced by the very hard work of many people, most (probably all) of them severely underpaid. In a fair world it will be these people the ones receiving the fruit of their labor instead of some rich bastards, but I don't think food will be cheaper, maybe even the opposite.

                    I understand the question, maybe you don't understand how the world works.

                      As AAA said in a comment beside me it isn't so much that I expect it would predate a space elevator. Simply that it is possible with current tech rather than still waiting on additional moderately likely breakthroughs like long chain carbon nanotube tether.

                      Also there are plenty of options to have the vast majority of the material be from space and not the surface since the core idea is a metal like copper being spun above orbital speed after being made into a full loop then used for the mag lev to keep at ground speed. There are absolutely a lot of astroids that might allow for that.

                          Capitalism means that they stop building before the price dips below wildly profitable, because capital is risk adverse. Capitalism won't, not can't, fix these problems.

                          Given that capitalism is a system, not an individual with intention, "won't" is the wrong word.

                              The viewscreen from Star Trek. It's actually real but nobody really wants to use it.

                              Phones, tablets, and laptops have had video chat for years. Apple brought it to actual TV a couple years ago. The idea is you use the Apple TV set-top box, and you get a squared-S-shaped clip that mounts an iPhone to the top of a TV so the rear camera array can point out into the room. You pair the two, and your whole TV turns into a viewscreen, just like on the starship Enterprise.

                              I've explained this to a few people and the reaction is usually "okay why TF would I wanna do that?" So imagine a Thanksgiving or Christmas, or other "big family holiday" thing where you have that one person who won't participate because it's their partner's family's turn to see the kids or whatever... so, the Apple TV is like $100. And somebody is gonna have an iPhone. And these days, everyone has a TV, at least in the west, and they're 55" or bigger. So you get the TV in the corner of the room and you set it up so you're broadcasting the whole living room and maybe part of the kitchen or dining room, and you connect it to another family/part of the family who is doing the same. And your TV is now a window into that other living room, and people can go up to the screen and interact, or wave from across the room. Now if it's like Thanksgiving and it's based around eating, you could even run the end of the table up to the TV (so the TV is basically sat at one end of the table with no one in between) on both sides so when you look down the table, you're looking into that other room.

                                  I've thought the same thing, Trying to hold a video call between families using a phone or even a laptop is such an awkward experience, especially if you want to just hang out virtually for an extended time like you said.

                                  But it wouldn't even have to involve a separate box or docked phone. Everyone's got a smart TV that can run apps, so all it should take is a USB webcam with a decent far-field mic.

                                  But yeah, in general I'm surprised this isn't more of a common use case.

                                    Edit: I removed the link. There are a bunch of really legit looking Foldimate websites and they are all scams.

                                        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.

                                        Roof-top gardens everywhere! Like the launch arcologies in SimCity 2000. They looked cool as fuck.

                                          UBI. Not only is it viable but it works in improving everyone's lives, not just the people receiving it.

                                          UBI would be amazing for the economy. It's basically Trickle UP economics. The money will still eventually end up in the pocket of some rich guy, but at least it will grease the gears of the economy on the way up.
