Normally, when foreign particles are introduced into the body, the immune system responds to destroy them. In the case of tattoos, though, the story is more interesting. As it turns out, our immune system does respond immediately when a tattoo is first inked. Cells swarm the damaged area of epidermis and dermis to try and deal with the invader. However, when these cells, called macrophages, interact with tattoo pigments, there’s a problem. The pigment particles cannot readily be broken down by the enzymes carried by the macrophage. Instead, the pigments remain stuck inside the macrophage until it eventually dies off and falls apart after a few days or weeks. Then, the pigment particle is ingested by another macrophage and the process begins again. Conveniently, just like skin, macrophages aren’t very opaque. This means we can still see the tattoo pigments even as they’re being swallowed and released over and over again.

Because I keep forgetting and it takes me far too much time to go through one of my million sites where I set this up and find the right config...

“We’re constantly being told that doing anything about the astronomical growth and the average size of motor vehicles would infringe on the freedoms of people to do whatever they want. But your freedom to swing your arm ends where my face begins, and SUVs are a giant punch in the face to everyone who doesn’t drive one. …

Over a ten-year period, over 500 American children were killed by being run over by SUVs – usually by their own parents, in their own driveways. This is insane! This is legitimately insane in any civilized society. This information alone would be enough to regulate the hood design of SUVs and light trucks, but instead the industry solution for this is proximity sensors and front-facing cameras, because car companies are happy for any regulations that means they can sell you more stuff. …

Fittingly, it’s almost been 10 years to the day I’ve posted about “Everything is a Remix”, and AI is no different.

Yes, it’ll affect us, yes, it’s learning from us, but we’re still the creators. And we’ve been doing the exact same.
