Well, to be honest, you still have to tweak and tune your AI model so that it works. Data speaks for itself. You have to run experiments, so the approach they have is going to be the same ANYWAY. AI isn't magical. It may just happen that both sides feel it is time for someone to take a new position. I think that's the better way to put it. But why this new guy not other seniors on the same team? That's a good question.
The tweak tune that I referenced as klunky wasn't the AI per se, but the way Google integrates it into the search results. Awkward enough that they would go more than a year between running/integrating it, and when it was deployed, the search results would swing wildy for weeks.
