The thing I hate about Wait But Why is he's got this whole "explain like you're five" thing going on but he writes like he's fucking Charles Dickens. And nowhere does he get to the point.

Here's the point.

If you unplug a USB cable and plug it into a hub, you can plug another USB cable and suddenly you have a USB interface between the two things that were plugged together. Isn't that nice. Do this with video cables and suddenly you have a character generator or a graphics engine or one of those cool swoopy things that allows the weatherman to push clouds around while standing in front of a green screen and wouldn't it be awesome if we could do that with, like, brains?

But anybody who so much as performs minor surgery knows that if you "unplug" any part of any tissue, the first thing that happens is it bleeds. The next thing that happens is it gets inflamed as a whole bunch of antibodies and white blood cells and platelets and shit jump on board to repair the injury. The next thing that happens is the body knits the wound site closed as best as it can and attempts to correct the damaged site, which it does imperfectly, which leads to scar tissue which is a shitty substitute for whatever was there initially but still trumps the ever loving fuck out of anything we've come up with to compete with it.

And anybody who has so much as talked to a cranky elder with a hip replacement knows that if you shove a foreign body in there before the body can do its thing, the body never truly stops attempting to close the wound. It makes a pearl of scar tissue over the invader. It hammers it with antibodies and platelets and white blood cells. The body no more accepts and gets used to implants than trees get used to nails and screws in them for tree houses.

And obviously Elon Musk is Einstein in a suit and obviously visionary billionaires know more about these things than mere scientists and obviously if he spent money on it it's clearly going to be a great success but here's a list of things Elon Musk lacks experience with:

- surgery

- medicine

- biology

- anatomy

- implantable medical devices

- wound care

- neurology

- neurobiology

- pediatrics

I've been in the labs where we put metal in animals. I've been part of the research where we attempt to trick the body into accepting an artificial substance as its own. I've talked to the guys attempting to map thoughts to cables. And you can want all this? And you can spend money to make it happen? But anatomy and bioengineering don't follow Moore's Law. And it's fuckin' great to put 300 cartoons on 10,000 words clear back to "in the beginning there were cavemen talking about rocks" but take it from me - this is the sort of bloviation you resort to when you want to obscure the fact that you don't know what the fuck you're talking about and I'm sorry, but one does not credibly write about "the wizard era" without making at least the briefest attempt at skepticism.

This guy's explanations actively make people stupider.
