Diverse routes.

If all of your connections go through a single conduit/path, you have a single point of failure, just waiting to take out everything.

I know you're making a joke, but this really is a (ihmo very interesting) mess:

In this case this is just multiple single points of failure though, at least for the larger ones.

If you lose one of the big red ones in the middle (common carotid arteries) you'll have a major stroke killing essentially three quarters of one of your hemispheres.

There's another pair in the spine (vertebral arteries, not visible) which supply the posterior and lower parts of your brain, but they're also not redundant. Also sometimes, one's doing basically all of the heavy lifting, and sometimes the other one doesn't exist at all.

Also this is a simplification and many many variations exist.

Look at the recurrent laryngeal nerve and try saying that again with a straight face.

Better yet, look at what it's like in giraffes

Obligatory post of the giraffe's recurrent laryngeal nerve taking a slight detour of 4.6m:

For anyone in dark mode: This image has a transparent background, it's much more clear on a white(-ish) background.

This is one of those great other parts of the body trying to catch up with an evolutionary change things, ha ha.

I had included an image, but it was an SVG. I was wondering, if that would show up on everyone's devices. I've swapped it for the PNG version now.

Religious people: "Our bodies were intelligently designed by an all knowing creator!!!"

The "intelligent" design:

If only Jesus had installed some service loops and hot spares in me, in case of hardware failure. For “gods perfect creation” I sure have a lot of design oversights.

I would love to see a human body with proper cable management

technically already is, considering the smartest way to “properly” cable manage the human body is to create as many points of potential failure as possible to mitigate an all-in-one death

geekworking said most of this i’m just the messenger

note: how the fuck do i link users

Not necessarily, evolution doesn't do global optimization, it does local optimization. Meaning that there could be more efficient solutions, but in order to get there you'd have to iterate through less efficient solutions, which is typically not the norm.

Risky click... I was half expecting a video of someone getting their cables ripped out.
