To accelerate AI adoption, Block intentionally dismantled its siloed General Manager (GM) structure, which had given autonomy to units like Cash App. They centralized into a functional organization to drive engineering excellence, unify policies, and create a strong foundation for a company-wide AI transformation.

Block's CTO reveals a counterintuitive lesson: reorganizing from a GM-based structure to a functional one (where all engineers report to one org) was the key to their AI transformation. This structural change had a greater productivity impact than any specific AI tool they implemented.

Google's competitive advantage in AI is its vertical integration. By controlling the entire stack from custom TPUs and foundational models (Gemini) to IDEs (AI Studio) and user applications (Workspace), it creates a deeply integrated, cost-effective, and convenient ecosystem that is difficult to replicate.

Google's Gemini models show that a company can recover from a late start to achieve technical parity, or even superiority, in AI. However, this comeback highlights that the real challenge is translating technological prowess into product market share and user adoption, where it still lags.

Unlike competitors who specialize, Google is the only company operating at scale across all four key layers of the AI stack. It has custom silicon (TPUs), a major cloud platform (GCP), a frontier foundational model (Gemini), and massive application distribution (Search, YouTube). This vertical integration is a unique strategic advantage in the AI race.

OpenAI is now reacting to Google's advancements with Gemini 3, a complete reversal from three years ago. Google's strengths in infrastructure, proprietary chips, data, and financial stability are giving it a significant competitive edge, forcing OpenAI to delay initiatives and refocus on its core ChatGPT product.

Google can dedicate nearly all its resources to AI product development because its core business handles infrastructure and funding. In contrast, OpenAI must constantly focus on fundraising and infrastructure build-out. This mirrors the dynamic where a focused Facebook outmaneuvered a distracted MySpace, highlighting a critical incumbent advantage.

Following ChatGPT's 'Pearl Harbor moment,' Google's CEO was seen as a lagging peacetime leader. He responded by issuing a 'code red,' restructuring the company, and empowering AI leaders. This decisive action transformed his image and positioned Google to aggressively compete in the AI race.

While Apple faltered with AI attrition and delayed features, Google executed a rigorous AI-first strategy throughout 2024 and 2025. This involved restructuring its AI organization and releasing groundbreaking models, directly leading to a stock surge that allowed it to overtake Apple's market capitalization for the first time since 2019.
