Beautiful software architecture historically mattered because humans needed
Beautiful software architecture historically mattered because humans needed to understand and modify systems cheaply.
With agentic engineering clean architecture is still crucial but its definition will change, shifting towards conventions optimized for machine maintainability:
explicit contracts
highly observable systems
automated verification
strong test suites
machine-readable specifications
modular context boundaries.
The best AI-era architecture may not resemble the most elegant human-era architecture.
