It's just such an old old business school idea. Metrics matter.
The classic example is the Second Fleet of convicts that were sent to Australia - they were paid per convict that boarded the ships. 40% of them died. Unsurprisingly perhaps, slave traders won that contract.
They started paying per live convict landed in Australia after that.
A COO at a ~$150B firm like Uber certainly should know what the outcome will be before the leaderboard goes up. Really makes you wonder if the board was incentivising him to increase AI usage; job done, bonus unlocked.
Or maybe it’s just what it looks like: A good old boys network of incompetent inbreds whose only qualification is that their parents could buy them memberships in the right clubs.
