agentic coding
McKinsey's State of AI 2026 survey found a third of organizations skipped a software purchase because agentic coding could build it in-house — but the share reporting real EBIT impact from AI didn't move. What that gap actually means for a build-vs-buy call, from someone who's made a few of them this year.
