Mat Marquis on Google pulling the web standards equivalent of U2 album marketing:
As a Chrome user, you’ll have received Gemini Nano in the form of a 4GB transfer recently; no permission asked or required. If you remove it, Chrome will re-download it. For reasons I can only guess at, Gemini Nano is presumably now considered to be part of Chrome itself, despite being a standalone product that is included alongside but not integrated into the browser — the way a copy of Bonzi Buddy included in a browser update might be considered a part of said browser.
It’s not exactly new news, as we’ve had published explainers on it for over a year now, as well as an intent to prototype for just as long.
Mozilla has already voiced its concerns/opposition:
According to Chrome’s documentation, to use the prompt API you must ‘acknowledge’ Google’s Generative AI Prohibited Uses Policy. Elements of this policy go beyond law. For example:
Do not engage … generating or distributing content that facilitates … Sexually explicit content
Do not engage in misinformation, misrepresentation, or misleading activities. This includes … Facilitating misleading claims related to governmental or democratic processesThis seems like a bad direction for an API on the web platform, and sets a worrying precedent for more APIs that have UA-specific rules around usage.
I have nothing to add, only that this is the sort of thing that seems worth knowing. Mat’s take-home isn’t exactly comforting because, remember, this has already shipped:
I’d like to say that something to the tune of “their whole argument hinges on ‘positive developer sentiment,’ so let’s show them that there isn’t any” — but there isn’t any; they cited places where there isn’t any. That’s not how it works for them. Google participates in the web standards process the way a bear participates in the “camping” process.
[…]
Remember this the next time Google announces an “exciting new standard” that they’re heroically championing — for you, for users, for good of the web — in language that has just a hint of inevitability about it.
The browser ecosystem has historically provided us with plenty of concerns. Alex Russell’s writing is a treasure trove of the current limits of browser choice. And things are especially murky when we need to be reminded that not all browser APIs are Web APIs.
