Uber Burned Its Entire 2026 AI Budget in Four Months — Here's the Bill Coming Due
Uber exhausted its entire 2026 AI coding budget by April — not an overshoot, a full burn. Beneath that headline sits a three-layer debt stack: technical debt, ungoverned prompt sprawl, and cost overhang accrued during a subsidised-inference era now ending.
