Agents Can Turn Office Into Plugins
- Satya Nadella's claim that "SaaS will dissolve into a bunch of agents" is plausible for single-user apps but threatens Office's centrality.
- Agents can read/write Office file formats (CRUD), turning Office from a work surface into plugin components controlled by new agent platforms.
Enterprise Needs A 4D System Of Intelligence
- Multi-user SaaS can't be fully replaced by agents because enterprise workflows need harmonized context, transactional consistency, and governance.
- A System Of Intelligence (4D map) is required to provide unified state, orchestrate actions, and ensure atomic transactions across apps.
Claude CoWork Demo Shows Agents Bypassing Office
- Anthropic's Claude CoWork demo showed an agent building spreadsheets and PowerPoints then sharing them to Slack, running workflows without using Office apps directly.
- The demo illustrated agents operating on Office artifacts via open libraries, with users living in a separate agent work surface.
