Retrospective Candor Is Still Candor

The most honest thing an enterprise executive has said about AI ROI this year was said only after the money was already gone.

Uber's COO told Fortune it's "very hard to draw a line" between rising AI costs and useful features for customers. The company burned its entire 2026 AI budget in four months. The quote ran on May 26. The budget ran out before that.

The optimistic read is that this is the turning point. A named C-suite executive at a major enterprise finally saying out loud what every CFO has been whispering. The vendor-led pilot era ends when one senior leader breaks the silence norm. Accountability conversations that were structurally deferred can finally happen. Governance catches up. Contracts tighten. The hype tax gets priced.

That read isn't wrong. It's just late. The Uber admission isn't governance. It's a post-mortem. Retrospective candor is what you get when an overrun forces an explanation, not what prospective discipline produces when it forces a conversation in January. The COO didn't say this with budget guardrails attached. He said it in May, after the burn was done. The honesty is real. The timing tells you what kind of honesty it is.

I don't know whether the board pushed this disclosure or whether it leaked through executive frustration with vendors that can't show their work. That gap matters. The two readings imply very different next quarters.

But — and this is where the bull read recovers some ground — the precedent outranks the timing. Once a named operator at a Fortune 100 publicly concedes the attribution problem, every CFO at every other enterprise has cover to ask the question prospectively. The silence norm doesn't break from the top down. It breaks from one named admission giving the next ten admissions permission to land.

Meanwhile, the Financial Times argued this week that AI is opening the door for smaller consultancies to wedge against the Big Four. The premise underneath that framing is that AI output quality is good enough to shrink minimum viable team size. Uber's disclosure questions exactly that premise. You cannot simultaneously argue that AI-assisted delivery is letting smaller firms match incumbent quality AND that a sophisticated buyer like Uber can't trace four months of AI spend to a customer outcome. One of those two claims is doing PR work for whichever side is telling it.

(If you're at a consultancy whose pitch deck includes the phrase "AI-augmented delivery," the Uber quote is the slide you have to address. Not in your next deck. In this one.)

Prediction: by Q3 earnings, three more named C-suite executives make a version of the Uber admission. They won't be brave. They'll be cornered. Boards will have read the Fortune piece. The first question on the call won't be "what's your AI strategy." It'll be "what's your attribution methodology." The companies that can't answer in specific dollars will perform their own retrospective candor in front of analysts who, unlike Fortune reporters, get to ask follow-ups.

The silence norm cracked this week. It cracked late. It still cracked.
