The marketing copy here is low quality. It spends a lot of words explaining what this isn't instead of what it is. It also just sounds like AI in an off-putting way. What does it mean to have an operating system with "Gemini at every layer"? Based on this page I fear that the entire OS will have a similar level of quality and consideration.
This paragraph in particular shows a confusing lack of understanding:
"The name itself is deliberate. ChromeOS came from Chromium — a metallic element ending in "-ium." Aluminium follows the same pattern, but the British spelling highlights the prefix Al, standing for Android-Linux: an honest acknowledgment of what this platform is built on."
The British spelling does not in fact highlight the fact that the word starts with "Al" any more than the American spelling would. By this point in the page I got angry and stopped reading, because it's a waste of my time.
Edit: if this is a parody, it makes way more sense. I fell for it!
