I'm not a medical person, can anyone who knows more than me explain exactly how cool this is? Fixing spinal cords, or just repairing simple nerve severance?

From the article, the device is more like a bridge rather than something that helps the body heal.

Neuropathy affects a lot of people. Diabetics, for example. This could improve a lot of lives.

I've always found it incongruous that we can move a person's body around the globe at 900 kilometers per hour for 25 hours for under $1500 but for 1000x that price and even with 1000x that time we can't bridge the distance between a brain and a foot.

You’re not thinking hard enough

Yeah, as far as I understand, it can act like a bridge between two ends of a severed nerve.

Individual science disciplines advance at a very uneven speed and with different start points in history.

We have always (OK, at least since Ancient Egypt) known more about mathematics than about physics.

We have always (...) known more about physics than about chemistry.

We have always (...) known more about chemistry than about our bodies.

The available technology mirrors that.

So, I'll put this into terms that a sysadmin can understand: imagine if all the Ethernet or fiber going to a datacenter rack was bundled up, and I cut that bundle up. Now you have to splice them back together so that every port is still connected to the same port it was before I cut the cables. Oh, and also, the cables are microscopic, incredibly fragile, and we don't know how to actually repair them. We sort of just hope they can grow back in place.
