It may well be that they also didn't have a product culture as an organization, but were willing to experiment or let small teams do so.
It's still a lesson, but maybe a different one.
With organizational scale it becomes harder and harder to launch experiments under the brand. Red tape increases, outside scrutiny increases. Retaining the ability to do that is difficult.
Google does experiment a fair bit (including in AI, e.g. NotebookLLM and its podcast feature are I think a standout example of trying to see what sticks) but they also tend to try to hide their experiments in developer portals nowadays, which makes it difficult to get a signal from a general consumer audience.
