Ep. 83 - Dark Data: The AI Problem Hiding in Plain Sight
If AI is only as good as the data behind it, we've got a problem.
In this episode of The STEMINISTS Podcast, host Phoebe Goh welcomes back Darnell Fatigati to talk about one of the least glamorous but most important topics in AI: dark data. You know, the forgotten files, mystery folders, archived documents, and digital clutter quietly piling up across organizations while everyone races to build the next AI breakthrough.
The catch? AI doesn't know the difference between your best data and your messiest data.
Darnell breaks down why dark data has become one of the biggest barriers to successful AI adoption, how it can introduce security, compliance, and reliability risks, and why companies need to stop treating data governance like a future problem. From AI copilots to autonomous agents, the smarter our systems get, the more dangerous unmanaged data becomes.
The conversation explores what it takes to uncover hidden data, build trust in the information that fuels AI, and create a foundation that can actually support AI at scale, without creating new headaches along the way.
And because STEMINISTS never leaves you without a fun fact for your next team meeting, stick around for a fascinating look at how AI helped researchers discover more than a thousand previously overlooked objects hiding in decades of astronomical data.
Key Takeaways:
Your biggest AI risk might be data you didn't even know you had.
Bad data governance doesn't just create compliance problems. It creates bad AI outcomes.
Before chasing the next AI trend, make sure your data isn't living in a digital junk drawer.

Phoebe Goh and Darnell Fatigati on dark data: the enterprise's hidden AI liability
Episode overview
In this episode of "The Steminists," host Phoebe Goh talks with Darnell Fatigati, principal product marketing manager at NetApp, about "dark data," information an enterprise collects, stores, and protects but never actively uses, classifies, or governs. Darnell Fatigati describes dark data as the enterprise's data estate blind spot: archived emails, file shares, logs, backups, old folders, collaboration tools, images, and videos that nobody can answer basic questions about, including who owns the data, whether it's sensitive, and whether AI can use it safely.
The central argument from Darnell Fatigati is that dark data becomes dangerous the moment AI tries to use it. Unmanaged data forces an enterprise to determine accuracy, sensitivity, access rights, and context after the fact, and that discovery work carries real cost. Darnell Fatigati distinguishes the stakes by AI type: generative AI built on dark data produces weak answers and hallucinations, while agentic AI built on dark data can trigger harmful actions across business systems, since agents plan, reason, call tools, and act.
Darnell Fatigati proposes a practical fix: start small, discover and classify data at the storage infrastructure level, and treat the work as continuous rather than a one-time project. Darnell Fatigati frames data management, not the AI model, as the hardest part of moving enterprise AI from pilot to production, and closes the conversation with an analogy comparing dark data to "jellyfish galaxies" recently discovered by AI in decades-old Hubble Space Telescope images.
Key takeaways
The following takeaways summarize the practical guidance Darnell Fatigati shared for enterprises managing AI and data infrastructure.
Dark data is information an enterprise collects, stores, and pays to protect, but doesn't actively use, classify, govern, or learn from.
Dark data commonly includes archived emails, file shares, logs, backups, old folders, collaboration tools, images, and video documents.
Dark data appears mostly in unstructured data sources, where metadata exists but remains undiscovered and unorganized.
When AI activates unmanaged data, the enterprise must determine its accuracy, sensitivity, ownership, and context, and that discovery work carries real cost.
With generative AI, poor data quality shows up as weak answers, hallucinations, and inconsistent summaries.
With agentic AI, poor data quality creates operational risk because agents plan, reason, call tools, and trigger actions across business systems.
Dark data risks include security leaks of sensitive information, data privacy violations, compliance failures tied to retention and access policies, rising costs, and degraded AI outputs.
Ownership of dark data is fragmented across an organization, which is why Darnell Fatigati says it becomes "everybody's problem" and therefore "nobody's priority."
The recommended starting point is discovery and classification at the storage infrastructure level, since that's where data lives and changes.
Managing dark data should be continuous, not a one-time project, because data moves, gets accessed, and changes constantly.
Solving dark data requires collaboration between storage, security, and AI teams, with each team contributing what it needs to know about the data.
The hardest part of enterprise AI isn't the model. It's giving AI trusted, governed, high-quality access to the right data at the right time.
Moving from AI pilot to production requires AI to operate on messy, distributed, constantly changing enterprise data instead of small, curated pilot datasets.
Topics and themes
This episode covers the risks dark data poses to enterprise AI and the practical steps organizations can take to discover, classify, and govern it.
Dark data definition: unused, unclassified, and ungoverned enterprise information sitting across structured and unstructured sources.
AI activation risk: how pointing AI at unmanaged data forces sudden, costly decisions about accuracy, sensitivity, and access.
Generative AI versus agentic AI stakes: weak answers and hallucinations versus operational actions that can harm customers or business systems.
Security, privacy, and compliance exposure: sensitive or regulated information sitting unmonitored until an AI agent accesses it.
Fragmented ownership: why dark data responsibility spans storage, security, and AI teams without one clear owner.
Infrastructure-level discovery: classifying and enriching metadata at the storage layer as a continuous, team-based process.
Pilot-to-production scaling: the shift from curated, manually supported pilot data to messy, distributed, constantly changing production data.
