Vertex AI existed as an ML platform before the GenAI era. DeepMind was doing it's thing in another silo. Then Gemini products came along. Then they acquired the Windsurf folks.
A smaller company would have no choice but to focus on one team and one product. Google has a Darwinian ecosystem and someone has to come along and smash teams together, clumsily refactoring the technology and user journeys.
Their employees read HN though and their VPs hear customers complain about onboarding. I hear there is an effort underway to create one unified agentic platform.
Eng was neutered at that large org. Product people had the "vision" and the say. A lot of product people just used our team's product as a stepping stone onto their next role and in the end it showed. I would hope Google has a better culture...but theres a good chance it doesn't.
