> It is understood that imaging techniques will eventually be good enough that artifacts may soon be studdied without disturbing the surrounding soil

Who understands that? It's very interesting. Is there somewhere in archaeology where it's discussed? Is there a paper or article? It might be interesting for HN's front page.

I have heard old time time tv episodes explain that. They were asked why sto digging a site and that was the answer. Archeology seems to be self aware as a discipline. The modern participants have been ham strung by earlier generations.

It is happening today. Chambers inside Egypt's great pyramid were detected in 2016 using muon imaging. It was a slow process but radically less damaging than the alternatives such as drilling test holes. More commonly, ground penetrating radar is regularly used to avoid digging test or exploratory trenches across sites. As resolution increases, fewer and fewer trenches need be dug. Scans are often used years prior to digging as a non-invasive way to confirm the existance of structures in aid of grant proposals. At some point, the scans will be the entire dig.
