The bottleneck has moved: AI is rewriting the Software Development Lifecycle

AI didn't remove the bottleneck in software delivery. It moved it.

For most engineering teams, writing code is no longer the hard part, the hard part is everything that comes after: review processes that weren't built for AI-generated output, product teams that can't define requirements fast enough for agents to act on, and token costs that nobody budgeted for.

In this piece, our CEO Fred Plais breaks down exactly where the pressure has moved, why individual productivity gains rarely compound into organizational velocity, and what the teams pulling ahead are actually doing differently.
