For decades, digital storage was so cheap that companies never had a compelling financial reason to clean house. The default operational strategy was simple: keep everything. Teams hoarded obsolete spreadsheets from 2014, unindexed network shares, duplicate system backups, and abandoned project channels under the comforting assumption that all data was an inherent asset.
In the era of Retrieval-Augmented Generation (RAG) and enterprise neural search, that assumption has become a major liability. Unmanaged "dark data" is no longer just harmless clutter occupying server space. It has transformed into toxic debt, directly corrupting internal artificial intelligence systems.
