In this 21st century we lived a controversy in the world of Earth Sciences. On the one hand, advances in computing allow us to simulate much of the phenomena that exist in nature, and we can also model remote places without accessing them. We have drones and satellites and advanced computing but it is still necessary to use the compass and scratch the rock with our geologist's hammer to capture the smallest details. There are very sophisticated analysis equipment but we cannot replace the human eye in the petrographic and geomechanical characterization. But what is the degree of precision of these computational approaches? To a certain extent the work of field data collection is being lost or the less relegated to a second position.
