Google didn’t announce a takeover. It just kept making Chrome faster, kept pushing PWA support, kept tying more services to a Google account - and at some point the browser stopped being a window into the internet and became the actual working environment for a significant chunk of people.
The numbers on Chromebook adoption in education have been public for years, but the more interesting shift is happening on Windows and macOS machines. More professionals are spending their entire working day inside a browser tab. Figma. Notion. Linear. Slack’s web client. Google Workspace, obviously. None of these require you to install anything. None of them behave meaningfully differently from a native app in day-to-day use. And all of them run inside Chrome, which is - by a wide margin - the dominant browser globally.
This Was the Plan, and It Worked
ChromeOS was never going to dethrone Windows in the enterprise. But it didn’t need to. What it did was establish the conceptual template: the browser is the platform. The underlying OS becomes commodity infrastructure. You’re not running software on Windows anymore in any meaningful sense - you’re running software on Chrome, which happens to be sitting on top of Windows.
This shifts leverage in ways that Microsoft has been slow to address. When a user’s entire workflow is browser-based, the value of a Windows license becomes harder to justify. ChromeOS Flex - which Google lets you install on existing hardware - is a direct expression of this logic. The OS doesn’t matter. The browser does.
The Part That Should Worry Everyone Else
Firefox has market share measured in low single digits. Safari is locked to Apple’s ecosystem. Edge exists and is fine but ships with Chrome’s engine. The practical reality is that the web platform - the standards body of what web apps can do - is largely shaped by what Google ships in Chrome.
That’s not a conspiracy. It’s just the compounding effect of having the dominant browser, the dominant web services, and a hardware platform (Chromebook) that makes the bet explicit. Web standards bodies include multiple stakeholders, and Apple pushes back through Safari in ways that matter. But the momentum is Google’s.
The browser ate the OS quietly, in the background, while everyone was debating whether Windows 11 was worth upgrading to. At this point, for a lot of users, it doesn’t particularly matter either way.
