Sundar and many of his executives have certainly read or heard of The Innovator's Dilemma, and I expect they're all moderately paranoid that it will be their downfall.
Also, that's not it. Google has a great ai app called Gemini where they have at various points hosted the top ai image generation model (certainly for speed, and for a while for accuracy) and have innovated with features like deep research
They are monetizing their ai conversations more effectively than OpenAI could dream of via ads and chat in Google search.
They are heavily investing in compute and talent.
When they've added llm results to Google search it has _increased_ engagement and re-engagement.
What part of the competition are they blissfully ignoring?
(I have counter arguments to some of these points, but I would rather hear other people's)
