Google definitely made errors, but it looks like it got them out of its system early in the game. They've been killing it since the summer.

The moment you knew they were serious was when they pulled Jeff Dean in and paired him with Demis. That was, I imagine, a very expensive move to make internally, (rumors are Dean had wanted to retire / move on), and Demis had nearly unilateral control of his corner of the AI universe at Google for roughly a decade. We're seeing the results of that move right now.
