Not true at all. This kind of thing has been going on for a VERY long time. Development of advanced imaging and chemical restoration of artifacts were being used back when I was in grad school forty years ago. The techniques have been hugely improved, especially by the addition of computer processing, but the basics are by no means new stuff.
As to ancient manuscripts, the scale, technical sophistication, and benefits of the current effort are far beyond anything we have seen before. Better preservation of artifacts is all for the good, but it is the recovery of otherwise lost ancient literature that uniquely offers a “Second Renaissance.”
