Is an obsession with "originals" as quaint as our desire to walk on Mars, rather than sending robots?

My first reaction (after amazement) was to imagine a machine coloring in the cracks. The future will always see any effort in this direction as primitive. Why didn't we wait for their tools?

A full-scale reproduction, recreating the feeling of the painting when it was new, doesn't have that problem. I want a robotic setup that scans, and 3D prints elsewhere with paint.

Meanwhile, does the art restoration world place a premium on using dissimilar materials, that prevent further disintegration while fooling the eye, but are easily distinguished by future scanning techniques? I can imagine purists insisting on "authentic" materials that will be confused with the original painting in the future.
