I've been watching the Ancient Apocalypse (S2) on Netflix and I had similar thoughts on discoveries. With drones and lidars we can discover so many of these villages/towns/cities, but the challenge would be to actually send boots on the ground and excavate into getting meaningful data/findings.
At the same time, the baddies (grave robbers, looters, etc.) can use the same tech and beat us to the game.
