  • Sometimes you get into skill issue, or time issues. I make some softwares that I need, but I don’t have advertising skills to make people use it.

    And sometimes I want to make something, but I don’t have the necessary skills.

    For example I’d like a local filesharing option. Where a single folder would be synced in my phone from home computer when I’m at home, and from work computer and phone when I’m at work. Without using cloud sync between them only when I’m physically traveling between them, that’s good enough for most use cases of cloud sync that I want for work.





  • I’m not an author, I’m a scientist. So I don’t know what the through process of authors are. But I it probably would take long time to actually find alternative ways to do the things same as us but underwater. The civilization won’t be like us, they would not have same technology, they wouldn’t have same values. Authors are probably trying to capture general population’s interests by making things they understand.

    And do you think “hey I haven’t heard anyone say something to me about earth rotating sun” would have been a good counter argument in the past.

    Water is incredible, we don’t know all the ways we can use it. Sometimes it takes hours to simulate what water does in seconds. Unlike other materials like metals, which are lot easier to predict. And if we’re talking about aliens, don’t even have to think water, it could be something else as flexible as water, while having properties that makes it easier to use.


  • Again, that’s because you are human, and you think your way is the only way.

    To make hydraulics you need metal

    How does your arm work? How does octopus move? You think you can’t make an structure like human arm, or octopus tentacles without metal, and then have a tube going through it in a way the water in it can move them. Look up soft robots. There isn’t just one way to tap into mechanical energy and move things. We did what we found first, improved on it. But thinking that’s the only way just shows narrow mindedness.

    You need to heat metal

    You don’t. You know aluminum used to be so expensive because you couldn’t really extract it from the ores like iron. Wasn’t found in pure form like gold. Then someone found you can use electrolysis to get aluminum from its ore. Then it became so cheap.

    You don’t just heat metal and put it in mold for every type of metal work. In micro scale there are 3d printing methods similar to electroplating, it’s very precise.

    And even if there is a need of heat, how can you say ocean doesn’t have it. A species could find out a way to tap into volcanic vents. Similarly how we use groundwater and rivers. They could use volcanos and geothermal energy. We do many many manufacturing processes under water in a tank containing water. They could make air tank and do things there too.

    Tech needs electricity and fire is not universal. That is what we use.

    Our brain is lot more complicated and efficient than the computers we make and it uses ions, in liquid media. So something that lives in water could definitely be able to make something that would be able to use similar things to do processing. Water is also really good with doing things, it’s flexible but doesn’t compress/expand like air does. Think about hydraulic systems. You can make them smaller and smaller as your tech progresses. Mechanical things using metals and such would work in water as well. Think about gold and such that can be used for electricity as well, we don’t use it because it’s valuable, but an alien world could have abundance of gold for them to use.
