## Resource

Legacy systems become liabilities not when they age, but when they block innovation and create unmanageable technical debt. This discussion explores how to transition from monolithic, high-risk architectures to composable, AI-ready environments.

## Highlights
- Main idea: Legacy status is defined by risk and opportunity cost rather than chronological age
- Practical takeaway: Plan system exit strategies and decommissioning from day one to prevent loss of institutional context
- Failure mode: Relying on 'if it ain't broke' logic while ignoring declining data lineage and accuracy
- Main idea: Composable architecture allows for swapping individual components without the trauma of 'big bang' migrations
- Practical takeaway: Prioritize observability and governance to ensure data trustworthiness in multi-vendor AI pipelines

## Topics

Technical Debt, Legacy Systems, Composable Architecture, Data Governance, AI Integration, Data Migration, Observability, Vendor Lock-in
