Uber's finance team has been surpassed by the engineering team in the use of artificial intelligence, with reports indicating that the company has already exhausted its 2026 AI budget. The extent of the budget blowout and its implications are unclear, but it has reportedly led to restrictions on employee access to AI software. The situation has also raised questions about the effectiveness of AI spending, with some suggesting that there is no clear link between such expenditures and useful product improvements.
