AI-Native to Quantum-Native Systems

A long-form strategic essay tracing technology waves from dot-com infrastructure and cloud/SaaS into AI-native systems, then toward quantum-native enterprise architectures. It argues that today’s energy, compute, labor, and security constraints are pushing the next transition: quantum-assisted decision intelligence, synthetic biology, fusion energy, orbital infrastructure, post-symbolic development, and quantum-ready cybersecurity.
