For 30 years, the closing mechanism was systems engineering: human practitioners who configured, extended, and worked around platform constraints. They managed the gap. They never closed it. And the expertise required to do even that is now retiring out of the market with no replacement pipeline. No university curriculum produces it. No certification program transfers it. The supply is contracting at exactly the moment the installed base of complex enterprise systems is at its largest in history.
AI changes the categorical answer. A reasoning system can now operate inside the enterprise perimeter with full access to private operational data, reason at expert fidelity using encoded domain knowledge, and execute through the platform's API surface without being constrained by the platform's configuration envelope.
Hero is the first closing mechanism in 30 years that is not constrained by vendor configuration ceilings, not dependent on scarce human practitioners, and not limited to what public AI can know about the customer.
That is the thesis.
