What are the chances that we're on the cusp of a golden age of archaeological discovery as robots/drones/etc advance in capabilities and allow us to deeply explore ruins, underground lairs, underwater wrecks, and other remains of past, buried civilizations that previously required human-sized openings / human-supportable environments? Or is it more likely to be continued marginal advancements over time as we keep discovering the next-hardest stuff to discover? (It's been decades since Alvin explored the Titanic, but the technology is getting much better and much more affordable.) Either way, it's an exciting time to be alive.
