The $9 trillion knowledge exodus
More than 30 million Americans will turn 65 within four years, and much of what they know has never been written down. eGain and Deloitte map the five-step path to capturing critical knowledge before it walks out the door.

In people’s heads. At risk.
THE GOAL
In the system. Trusted.
Knowledge has value only once it crosses from expertise into an authoritative, AI-ready foundation.

What the article covers
Awareness is not the problem. Action is.
The retirement wave is well understood in boardrooms, yet most organizations still have no systematic way to capture what departing experts know. As average job tenure falls, the deep organizational memory built over long careers is unlikely to reaccumulate on its own.
The article makes a sharper point for anyone rolling out AI: deploying it on fragmented, poorly documented knowledge amplifies the gaps rather than closing them, and erodes trust in the output. A trusted foundation is the prerequisite, not the afterthought. From there, the piece lays out a five-step process that turns a demographic risk into a durable capability.
The five-step process
A structured progression, not a set of disconnected initiatives.
1
Build a trusted knowledge foundation
Consolidate scattered content into a single authoritative source that people and machines can rely on. This is where AI readiness is won or lost.
2
Prioritize the knowledge that matters most
Use interaction analytics and a risk heatmap to find the critical 20 percent of content that resolves 80 percent of issues, instead of trying to document everything.
3
Capture departing expertise systematically
Distribute the work across an Expert, a successor, and the wider team, and accelerate high-risk areas with time-boxed knowledge sprints and AI-assisted drafting.
4
Align the organization to share
Address the human factors. Tie knowledge contribution to performance, recognize experts at senior levels, and secure real executive sponsorship.
5
Capture knowledge in the flow of work
Shift from one-time projects to a continuous capability by harvesting insight from the collaboration tools where work already happens.
Is your knowledge AI-ready?
The first step is a trusted foundation, and AI only amplifies the gaps in fragmented content. The AI Content Readiness Assessment shows you where your knowledge stands and what to fix first.
