I mean, yeah, implants will always be shit.

This is a discussion I have whenever implants come up, because people such as yourself think that Moore's Law applies to immunology. It doesn't. Until we genetically engineer humans to specifically not reject a specific selection of foreign materials, humans will continue to reject all foreign bodies. The way around it, which I worked on back when I thought I wanted to do this shit for a living, is to engineer nanostructures small enough that the body doesn't attack them... but since the body attacks, you know, viruses, you start working with structures about the size of asbestos fibers which, by the way, are carcinogenic. Or, you know, you CRISPR up your babies so that they think titanium is a part of their bodies and then within ten years you've got viruses and bacteria that imitate titanium.

That's the other part of the problem: because any implant site is a wound, any implant site is subject to opportunistic infection and everything else has a much faster evolutionary cycle. I can't remember the exact numbers, but the number of generations humans have experienced since Australopithecus is the same as drosophila have experienced since the 1930s, and e.coli have experienced since two weeks ago. Being long-lived means you have a lot of genetic inertia, for better and worse.

The "right" materials, as you outline them, are materials that go away. Did you miss that?

Here, we report materials, device architectures, integration strategies, and in vivo demonstrations in rats of implantable, multifunctional silicon sensors for the brain, for which all of the constituent materials naturally resorb via hydrolysis and/or metabolic action, eliminating the need for extraction.

They're dealing with the very problem I describe: leave the implant in and it will kill or maim the patient. Your answer? Grey goo.

Theoretically, nanomachines can turn my stale coffee into diamonds. Practically, a nanomachine is a tiny, rudimentary thing that requires preposterous amounts of support infrastructure to do something really simple in miniature. A future in which that sort of omnipotent nanotechnology exists is one that belies implants entirely: why should I worry about an interface jack that doesn't rot when I can just have the magic grey goo restructure my brain while I wait?

I get that the guy is colourblind. My point is that there's no aspect of a singing camera that needs to be surgically attached to your body. That's an iPhone app, yo.

No part of that needs to be surgically stitched to you. My suspicion is that he decided to be hipsterish about it and spike a transducer into his skill so he got it via bone conduction but fuckadoodle doo. My library sells earbuds for a buck a piece. The reasons for not stitching that shit into your skull are legion.

Also lesion.

I'll show myself out.
