      It’s all massive spaghetti code too, including spaghetti wiring. Terrible cable management.

        a 3D model of a human neck with arteries, veins, lymph nodes, and nerves, shown all clumped and tangled together, labeled "That's bad cable management. Pull them out."

          A giraffe has a vein or nerve that goes all the way up to its head for zero reason.

          It’s incredibly inconvenient and difficult, but it wasn’t before their necks were absolutely stupid.

            That would be the laryngeal nerve. It’s been with us vertebrates for a long time.

            I take your, “for zero reason,” to indicate that it’s silly that it’s so long in a giraffe. And it is, because it connects the larynx and the brain, two bits that aren’t very far apart. You’d never design it that way from scratch.

            But the laryngeal nerve’s length has a reason: it loops around the heart and it developed in our fish-like ancestors. At that time, it wasn’t silly for the nerve to wrap around the heart, because fish don’t have necks and thus the nerve was about the same length whether it wrapped around the heart or not. As necks developed, evolution found it easier to lengthen the nerve than to reroute it. So here we and giraffes both exist, having much longer laryngeal nerves than you’d engineer if you were making us from scratch.

                  On one hand it sucks most people didn’t get the reference.

              The issue is that it traverses the neck twice, going all the way down from the brain and all the way back up to its endpoint.

          Your “good cable management” would be terrible for cooling. These cables are multipurpose, and their spaghetti flow is a feature.

              Not really that fragile, you (generalizing for most of Lemmy) just put excessive strain on it by sitting at a desk and using a computer.

              The other big one is brachial impingement because you all slouch and your shoulders get so fucked up they pinch the nerve for 90% of your fuckin arm.

        Yeah, as I commented elsewhere, I’m damn impressed my code managed to compile and run. I guess life has a pretty fault-tolerant compiler at times, or maybe I was just super lucky to not have the errors be in spots that’d completely screw me over.
