AI is making it possible to capture and share a person's judgment—not just their knowledge—by turning years of experience into systems others can learn from. However, the most valuable expertise is often tacit and can't be fully documented, so the best approach combines structured knowledge with apprenticeship, using AI to preserve what can be written down while relying on human mentorship to pass on intuition, context, and judgment. Rather than replacing experts, AI gives them a way to extend their expertise beyond themselves and create lasting institutional knowledge.
