How will AI agents fundamentally change software architecture and the way organizations interact with SaaS applications?

AI agents represent a paradigm shift in software architecture comparable to the introduction of relational databases. Unlike traditional SaaS applications that operate in silos, agents will orchestrate operations across multiple applications simultaneously, breaking down data barriers and creating unified workflows. This transformation changes how users interact with business software. Instead of logging into separate systems like CRM, Office365, or other applications, users can query an AI agent that seamlessly accesses and integrates data from all these sources. Nadella's personal example demonstrates this - he now queries his CRM database daily through Copilot, something he rarely did when it required direct system access. The result is a fundamental restructuring where traditional CRUD operations are orchestrated at the agent level rather than within individual SaaS applications, making data retrieval effortless and workflows more efficient.
