Asana had estimated it would take five years to replace an outdated testing system. Using OpenAI Codex instead, they got it done in just two weeks for about $12,000. See the original article for full details.

πŸ’¬ JudyAI Lab Take

Asana originally figured it’d take five years to replace an outdated testing system. Using OpenAI Codex to rewrite it instead, they finished in two weeks for roughly $12,000. That gap between the original estimate and the actual outcome is worth paying attention to if you care about AI development efficiency.

This case points to a trend that’s taking shape: the technical debt inside large systems that nobody wants to touch because it’s “too painful” has historically been stuck behind human hours and time budgets. AI-assisted coding tools are now cutting rewrite costs dramatically, pulling projects that once seemed off the table back into feasible range. The takeaway for AI builders isn’t the surface-level “AI is faster than humans” conclusion β€” it’s that the five-year, ten-year thresholds you calculated based on human labor hours may no longer be the right baseline. They need recalibrating.

Looking at the legacy systems your team has been putting off indefinitely β€” is it possible they’ve just been stuck there because the human-labor cost estimate was too high?
