CTOs Agree: Cognitive Debt Is the New Technical Debt

CTOs gathered at a dinner in Toronto discussed AI adoption in engineering, concluding that the era of unlimited AI spending is over and organizations now need measurable ROI within 12 months. The key challenge is that AI costs remain largely unmanaged—measured in tokens rather than headcount—making it difficult for CFOs to model actual investment and return. Engineering leaders agreed the pragmatic path forward is to standardize AI tool usage and establish baseline metrics before pursuing ROI targets, while hiring practices should emphasize system design thinking and product leadership alongside technical fundamentals.
