The point was something that was made by people in the past is not replicable by modern technology today. Wootz steel is one of those.
Are you thinking that modern technology can create effects that are not inherent in the original object?
Example; the 3D effects digitalized from the shroud?
Wouldn’t this be a set back to the study of archeology ? how can we trust evidence if the methods of modern technology create phantoms or simulacra or reality?
And if not the evidence, are we not sliding into postulating an absurdity?
So are the pyramids.
