What specialists try to do is get at least three imaging processes that are totally different from each other. Then you can run these through a computer program and make a composite image. In one scenario you suspect a brain tumor, so you image the brain tumor with PET scans, MRIs, and CT scans and create a 3D model. The doctor opens up the skull to excise the cancer, but they can't see anything. Do you cut out what's supposed to be in that spot or not? The current story is yes, you believe the images over what you see with your eyes.

I can't experience my brain because I'm inside of it. If you're imaging your brain, you can also find scary things. As one ages, your brain shrinks. And how much it shrinks, and where it shrinks, relates to conditions like Alzheimer's and dementia.

I remember reading about a court case where a man tried to stab a judge with a pencil. There are Google pages full of similar instances around the world. It's obvious that the pencil lends itself to precisely that kind of use. It's not as lacking in dominance as you might think. I have an article on the fallacy of the designer intent because a lot of designers think they can design uses into technology. You can't do that. I use the pen, I make the mark, but the pen is also using me. The pen could be said to be allowing these kinds of marks. I can't do just anything with the pen.

I never went into aesthetics. Aesthetics is what philosophers have to say about art, and a lot of them take an analytics position and raise the question, "What is an art object?" As soon as you fall into that trap, an artist is going to come along and say, "That isn't art - it's something else." That's a hopeless gig.

Definitions get you into that time trap, and I'm very much more process-focused. Take Lucy, for example. Lucy is famous largely because she has almost a total skeleton. The more sophisticated we get with instruments, the more we can find out. Through CT scans of her skeleton, they now think she died falling out of a tree because of the way her bones are broken. If nineteenth and twentieth century technologies can retroactively transform our bodiment, what then do the technologies we now use do?

You have a long history of changes in diagnosis, from no touching to touching, to assessing acoustics and visuals. But visual is a problem, because if you're a living being you can't see beyond the surface of the skin. Now you don't have that problem. Laparoscopic surgery, inserting a camera into the body, is sometimes called "Nintendo surgery" - the best training for laparoscopic surgeries has actually been video games.
