There is a growing narrative that AI will replace SaaS. The argument usually goes something like this: if software can perform work autonomously, then we no longer need software tools. Instead of Software-as-a-Service, we’ll move toward "Service-as-Software" systems that simply deliver outcomes. This framing seems compelling, but it misunderstands what SaaS actually is.

The diagram I’ve been building toward (the foundation of a new series launching on The Doc Landscape called The Living Knowledge System) maps the system that product knowledge actually moves through in a software company. Not all knowledge in a company. Not HR onboarding or sales enablement or anything else. Specifically the knowledge that’s born…

If documentation is now part of a living knowledge system, then the role responsible for it has to evolve as well. The shift happening in documentation work isn’t just about new tools or faster workflows. It reflects a deeper change in how documentation is understood.

For a long time, documentation followed software. Products were designed, built, and shipped. Then documentation came afterward. Today, software is designed and built while documentation is created in parallel, and both ship together. Documentation is no longer cleanup work. It’s part of delivery.
