Developer Uses Claude AI to Build Free Open-Source Word, Excel, PowerPoint Clones

The significance lies less in the clones themselves than in the cost curve they illustrate: if a single developer plus an AI assistant can approximate established productivity suites, the moat around mature software narrows. Incumbents whose pricing rests on feature depth rather than switching costs are the ones most exposed. The open question is whether rough AI-generated replicas can be maintained and hardened to production quality, or whether they remain demos — and whether this pattern extends from consumer apps into enterprise and RWA tooling.
