AI makes the need to address market risk before you build even more urgent. It can generate code, prototypes, and experiments at machine speed. But speed does not equal insight. We need a compass before we accelerate.
If you do not know what is worth building, you just reach the wrong answer faster, and waste more resources.
I explored this in my latest newsletter article by reviewing The Enterprise AI Playbook: Lessons from 51 Successful Deployments by the Stanford Digital Economy Lab:
What Stanford Found Stanford's Digital Economy Lab spent five months interviewing executives at 41 organizations to document 51 enterprise AI deployments that delivered measurable value. The Enterprise AI Playbook, published in April 2026 by Pereira, Graylin, and Brynjolfsson, reports that 77% of th
