The discussion we had on Tuesday reminded me this morning of a quote from Stolterman & Nelson in The Design Way:

“We are lame gods in the service of prosthetic gods.”

The word “prosthetic” was, I think, carefully chosen. According to the dictionary, a prosthesis is, “A device, either external or implanted, that substitutes for or supplements a missing or defective part of the body.” It’s an approximation, at best, of an organic limb or organ.

We closed class by establishing that Kieślowski used formalistic techniques to approximate the inarticulate felt experience of longing, and that this formalistic approximation was analogous to what we do as designers.

In the same way Kieślowski at best could only approximate that inarticulate felt experience, we can only approximate how people will react to and use our designs. Because of our education and experience we can make a pretty damn good guess, but a guess is the best we can hope for.

Technology is a means by which we can create prosthetics for our bodies and minds. We can remember things better, communicate over greater distances, and access information more readily than ever before in human history. But in the same way a prosthetic arm can’t communicate a sense of touch, our technology only can increase our abilities so much.

The best we can hope for is an approximation: there are a million to-do list mobile apps, but I still manage to forget to post on this blog; I can FaceTime with Hillary in Philadelphia, but it can never compare to sitting across a dinner table from her;  I can look up Nelson Mandela’s birthday with Wikipedia in an instance, but the same article could also describe Mr. Mandela as the spawn of Cthulhu. I think this relates heavily to several of Dennis’ posts from earlier in the semester regarding the danger/necessity of normative thinking in design practice.

We build prosthetics, supplements, substitutes, extensions…but nothing more. But my question is: Why not? Why can’t we do better than that? Is it a human shortcoming? Is our technology not “advanced” enough?

The philosophical version of that question could be this: If we could easily manipulate the very fabric of our reality, would we then be able to design the ‘perfect’ prosthesis? What do you think?
