Devs are coding faster. Coding reviews are eating the gains

AI coding tools are boosting developer output, but the gains are being offset by a sharp rise in review, testing and security work, shifting the bottleneck from code creation to code trust. For CIOs, the strategic takeaway is that simply buying more AI tools will not accelerate delivery unless IT redesigns workflows, embeds automated verification, and measures end-to-end software throughput rather than coding activity alone.
