Quantum-resistant zero trust architecture for MCP hosts

**Executive Summary:** This blog post examines the rise of cognitive AI in business and the practical challenges of designing, deploying, and governing autonomous agents—covering architecture and lifecycle design, resilience and failover, identity and access management (RBAC/ABAC and zero trust), MLOps practices (versioning, monitoring, cost optimization), ethical and explainability concerns (bias mitigation, auditability), and psychological risks such as cognitive offloading—ultimately recommending modular, auditable systems with human-in-the-loop controls to preserve safety, compliance, and human judgment.
