Code generation speed isn't the bottleneck — coordination and review are¶
Insight: AI collapsed code generation cost to near-zero, but most teams kept the same playbook built on the assumption that writing code is expensive. The actual time sinks — pre-meetings, prioritization, design committee, tech spec reviews, backlog wait times, code review, QA cycles — remain unchanged. The bottleneck shifted from code generation to review and coordination. Companies that succeed aren't adding AI tools to existing workflows; they're changing the underlying systems.
Detail: Steve Sewell (Builder.io CEO) argues the shift is from "writing code is the holy thing" to "merging code is the holy thing." Production-grade prototypes using actual codebases and design systems (not throwaway demos in no-code tools) enable teams to get 80% done versions faster than they could have a meeting about what to prioritize. Discussions change from speculative alignment to reactions on tangible artifacts. The fastest teams put one person end-to-end on features, collapsing the PM→Design→Eng→QA handoff chain.
