    There are a few flaws with that in reality. One is too much risk consolidation. Having every artery in the same place means that it’s a very easy target for animals or other humans. Another is that it requires far more complexity to actually distribute resources isometricly relative to their need. It’s also easier for disease to grow tumors in a giant mass of blood vessels since they are very homogenous. Another downside is that heat is not distributed evenly so it greatly increases the amount of energy that has to be spent on building auxiliary blood vessels which means the animal has to eat more to achieve the same reproductive success.

    Life in reality is balancing many things. Thermal efficiency is a big one, material efficiency is another. Defensibility is a big one, and also genetic simplicity is another. Your body is procedurally generated, not created from a blueprint really. Cells create structure via functional logic in large part, although there are hox genes which encode some basic directionality and relative spatial cell differentiation based on its neighbors and the proteins they are presenting on their membranes.

    In other words your body is generated more like a Minecraft world and creating very clean wiring and tubing even if there was pressure for it, would be something that would require a ton of genetic complexity. More complexity means that every single cell has to copy these extra hundreds of genes whenever it copies it’s DNA, which raises the overall thermal and nutrient cost linearly. This is the reason people are beautiful on the outside but on the inside look very strange. We do put many of our evolutionary resources into beauty but not in places where it will likely never be seen.

    Are those zipties? I fucking hate zipties whenever cleaning out old installs. They’re just about always so tight it feels uncomfortable to cut those when youre dealing with fibres or just about anything, really.

    I use velcro ties myself most of the times. If I absolutely have to use zipties, I leave then so loose that they’re just guiding the cabling, not choking it.

    Just today I cleaned out one +15 years old install and oh boy, multiple zipties there. Awful

    I think the funniest part of this post is the nightmares people are getting from zip ties.

    The extreme detour of the recurrent laryngeal nerves, about 4.6 metres (15 ft) in the case of giraffes,[32]: 74–75  has been cited as evidence of evolution, as the nerve’s route would have been direct in the fish-like ancestors of modern tetrapods, traveling from the brain, past the heart, to the gills (as it does in modern fish).

      Intelligent design. Same with our eyes 🤣 just put them in backwards and thread the cables through the retina; genius. Octopuses are clearly gods chosen “people”.

        The intelligent design geniuses argue that the eye is too complex to have evolved.

        “Of course it didn’t evolve like that! It started with a patch of light-sensitive cells and worked it’s way up from there. And that’s happened more than once.”

        They have to think evolution means that creatures and features popped into existence fully formed. Not only because that’s how the Bible tells it, they can’t comprehend evolution on a 7,000-yo Earth. And neither can I!

        You’ve got the killer argument though. “Why didn’t God bother to make our eyes like he did with the octopus?”

              His theological understanding of pokemon was convoluted at best, haha.

              He swore up and down that pokemon trainers were witches, and the pokemon were demons they could summon to act as their familiars, and their evolution was symbolic of how much satan’s power had corrupted the vessel.

              Like, he thought you started with a mouse, then summoned a demon into it and bound it to make it your familiar, turning it into Pikachu. Then as Pikachu evolved into Raichu, that was a sign that satan’s power is further corrupting the poor mouse, one of god’s creatures.

      The same nerve also exists in giraffes and does the same thing so it is consequently fucking massive.

      Is it though? There isn’t one part in the human body that has exactly one specific purpose. Everything is something mushy with basically one main purpose and a ton of side-quests. Almost the exact opposite of what engineers prefer.

        I dunno, eyeballs are pretty much unitaskers. Vision gets used to help reinforce balance, reflexes, and proprioception, but that’s all in the brain.

        Teeth might be debatable. Arguably they’re only for masticating food. The debate opens up whether other functions are physiological and so compulsory, social constructs, or neurological things we do instinctively.

        With everything else, I 100% agree. It’s all an engineering nightmare to service and troubleshoot.

      “Commander Riker has dramatically demonstrated to this court that Lieutenant Commander Data is a machine. Do we deny that? No. Because it is not relevant. We too are machines, just machines of a different type.”

    God wiring his new creation: … oh yeah I need a cable for the heart … oh yeah, I need a cable to power the lungs … oh yeah, almost forgot, need a cable for the liver … oh yeah, need a cable to control the legs … oh yeah, need some sensor lines for the hands … oh crap, wired the genital sensor lines wrong … oh shit, no more room for the lines for the kidneys, maybe if I wire it this way … shit, need more power lines for the stomach … crap, need more sensor lines here … shit, shit, shit, I need more power lines

          We let the original customer, ~~~~, ride his ZX-11 RB Racing Intercooled EFI Turbo around the block and then disabled it as he was moving to Tennessee. He was amazed how “perfect” it was. We told him he could have the missing parts when he owned up to what he had done and pay for any losses we had. He was a coward and did nothing. He sold the bike to a friend of ours to avoid dealing with us, who paid us for the missing parts, getting a $17,000.00 motorcycle for $6,000.00.The bike ran 210 mph on it’s first pass at Maxton. The seller, ~~~~, was there to see “his Bike”. Last seen after collecting a large insurance settlement for being run over by a double dump truck/trailer in California, ~~~~ was chroming parts for pinball machines in Gallatin, TN…Does he have a chrome shop…no he doesn’t. We were happy to hear later on that he lost his left leg in another motorcycle accident…and were glad it was his left shifter leg. Acting as a middleman for chroming is safer than motorcycles for him. He used to laugh about how he was charging people $400.00 to ground one wire in a GPZ750 turbo ecm. Cosmic pinball got him. Karma. In the finality of this “what goes around comes around” ~~~~ hit a turkey vulture on a motorcycle in 2016 and was killed. We hope the turkey vulture survived.

          Incredible levels of vitriol. I need to keep practicing

      They show up in the worst places. Top offenders are inside A/C units and car engines. Yanno, where there’s lots of vibration to help the little bastards cut through insulation.

        Huh… Cutting insulation is a new one for me. I’ve seen it with adel clamps that chewed through their grommet but never nylon.

        Were they in areas where the wires needed to be allowed too mice but were too constricted?

    Going through a DC consolidation project now and the line techs are fucking clean. I’m slightly excited to overnight patch so I can make this place look good.

    I can finally make this mess I walked into look good.
