Welcome, deep divers, to the fourth and foundational episode of Season 2 of The Deep Dive, brought to you by ACMO! In this monumental journey, we trace the incredible history of how humanity has grappled with the information fog and sought to intelligently navigate vast oceans of knowledge, from ancient libraries to the internet's digital expanse. This isn't just a story of technological breakthroughs; it's an epic tale of how search has transformed human cognition itself. As we'll discover, we're no longer just "finding it"; we're moving towards a world where search engines are truly understanding and answering – a seismic shift in our relationship with knowledge.

Join us on this incredible journey to understand how search is fundamentally changing what it means to be informed and how it's shaping our future!
