If you design for an ephemeral state, it doesn't make sense to be long lasting.
3D printing a door handle that perfectly fits my hand, my door, the space it moves in and only lasts until I move to another house can be the ultimate perfect design _for me_.
I'd see the same for prosthetic limbs that could evolve as the wearer evolves (e.g. growth up or ages) or what they expect from it changes.
