It would have gone much better for Google if the Brain team had been permitted to apply their work, but they were repeatedly blocked on stated grounds of AI safety and worries about impacting existing business lines through negative PR. I think this is probably the biggest missed business opportunity of the past decade, and much of the blame for losing key talent and Google's head start in LLMs ultimately resides with Sundar, although there are managers in between with their own share of the blame.
