The consequence is that they waste money and time. Which actually matters for businesses strapped for money or time. But most of the megacorps are swimming in money and in time. They waste those all the time even without the AI because the upper management accepts kickbacks to contract with the worst (but also the bribiest) contractors. And mid management, and everyone else, put their own personal interests ahead of the company's. Now that the AI hype is here, they have a new tool to waste time and money with, but nothing has fundamentally changed. Big business is a lumbering inefficient bureaucracy by its nature.
