Perplexity Engineers Build CobbleDB with AI Agents
KEY FACTS
- CobbleDB is a storage engine developed by Perplexity.
- The engine was built entirely by two engineers collaborating with AI agents.
PHYSIX OBSERVATION
Building a database engine with just two humans and AI demonstrates that large models have achieved exceptional productivity in low-level complex system development. If this model proves replicable, it could significantly lower the barrier to entry for foundational software R&D, reshape engineering team structures, and signal the accelerated arrival of the 'super-individual' era.
