    Gold is already worthless, main purpose of gold is that its shiny and pretty, less than 1% of gold mined gets used for electronics and stuff. The rest ist accessoires. The only reason gold costs something is because people think that it is worth something.

      Gold does have practical value. It doesn’t oxidize or tarnish at standard temperature and pressure, it is soft enough to beat into shape with a hammer and it can be rolled out incredibly thinly. If it were as common as iron, we would see it used everywhere. Gold sewer pipes, gold roofing, even gold foil to wrap your sandwich.

        If I remember correctly, even its conductivity is higher than copper. Maybe in an alternative reality, we’d be using gold cables

          It’s not, but its main benefit is that it didn’t tarnish or corrode. Copper is the second must conductive metal, with silver actually being the first.

          Gold plated contacts are fairly common on various cables and plugs, it doesn’t take much gold.

            I could see them attaching rockets to it to try this. Or maybe move it into earth orbit to mine it.

            If they brought it to the surface what happens when it goes through the atmosphere? Does gold “burn”?

              Does gold “burn”? Not in the common sense, but it can both melt and vaporise (at about 1000 C and 3000 C respectively). It can also form stable oxides, and is probably more likely to do so when condensing from a liquid or vapour state mixed with air. So the answer is twofold: A lot of the gold would melt vaporise before precipitating as very fine particles that are spread with the wind, while an amount of it would likely form oxides in the process. The result would be a bunch of gold and gold oxide dust spread over a vast area, probably taking years before all of it reaches the ground.

              Not if that size is accurate. gold price at 10^5 EUR/kg, a quintillion being 10^18, makes 10^13 kilos, at ~20000 kilos per cubic metre 5*10^8 cubic metres, or a block of 1000x1000x500 meters (~ sphere of 1km diameter), and that’s only for a single quintillion, and assuming it’s all gold, no rock. Nothing of that size burns up on atmospheric entry

                Thanks for doing the math. I was wondering if some portion of the gold burns off. Also does it kill us all on impact?

                  I just got home to use a proper calculator instead of estimating in my head, and with 700 quintillion (as per the screenshot / meme), and gold density less “roundabouted”, at 19000 kilos / cubic metre, this would be the same as a solid gold sphere of 8.9 kilometres in diameter (3rd root of 700 is 8.88 - and wow, my rough estimate of 1km for 1 quintillion was spot on! :)

                  And yes, that would absolutely be a planet killer asteroid. I don’t see how anything but primitive life forms on Earth could survive that: https://www.space.com/asteroid-apocalypse-how-big-can-humanity-survive

                  To be honest I don’t know (also not OP) but if the gold is one solid chunk there might be chance that it will function as a large enough heatsink that it wont “burn”… But then again it’s probably not just one chunk… So some of the outer layers might “burn” as you say, but the gold atoms are not lost. That would require a nuclear reaction… Instead some of that gold would turn into liquid, and some would turn into gas. In this state it might reach with other elements in the atmosphere, but if it doesn’t it will turn back into solid form again when it cools. In that case the result would be microscopic gold clumps spread over a huge area.

                    That makes more sense, thanks. So those pieces would be harder to recover. I’m trying to figure out how much of it they lose in such an operation. Is it like half of the amount? Or is it like single digit percentages?

                    I suppose even if they lose half, it would still be better than trying to put it in earth orbit and trying to mine it there. So ultimately that would be the preferred approach.

                    And maybe not kill millions of people in the process.

          Motherboards used gold before. Recyclers make a good profit finding old motherboards just for the gold.

        A lot of people live their entire lives only being shiny and pretty and have a pretty good go of it.

      Yes, and you’re making my mental gears turn. The only reason gold is worth something is because some regulatory power says it’s worth something. As soon as they say it’s not worth something that will be the end. As for now, some thieves go to Costco with stolen credit cards and they buy thousands of dollars of gold bars to resell. 😡 For that and many other reasons, I think gold should be demoted to the worth of arid dirt.

        Gold is a valuable catalyst in chemical industry, and has value as a very efficient conductor that is very malleable and corrosion resistant. Sure, most of its market value comes from people wanting to put it in jewellery and other decorations, but it’s objectively far, far, more valuable than most other materials.

        Gold is more useful than copper or silver. If there were enough of it, it would be used as a coating because it doesn’t oxidize, and in connectors and wiring due to it’s low electrical resistance. It’s commercial value is the reason it became the monetary standard.
