Start with what an opt-out can actually reach. Meta can honour a preference expressed inside an account, and privacy law caps some collection outright [4]. Neither instrument touches the person standing in the frame, and Fast Company is blunt that people who never use Meta products still become data points when others record, photograph or mention them [12]. That is not a gap in the consent flow. It is the category of material a contextual agent most needs, because the useful part of egocentric capture is other people.
The clearest sign that the hardware follows the model rather than the reverse is Project Aria. Presented at Connect 2020 as an AR research project, it is now also used for AI-focused behavioural research [8]. In the same keynote Zuckerberg put the route to an "ultra-low-friction contextualized AI interface" through EMG and egocentric data [7], and recounted a 2019 visit to EssilorLuxottica in Italy to work on glasses design [8].
Twelve years separate the first Facebook AI lab from the standalone Meta AI assistant [1], with Yann LeCun hired to run that lab in December 2013 [5] and the WhatsApp, Instagram and Messenger infrastructure merge announced in 2019 [6]. Ray-Ban Stories shipped in 2021, a month before the metaverse push [9]; Horizon Worlds is now shut while the glasses line continues [2]. Read as a portfolio, the piece Meta discarded was the destination, and the pieces it kept are the capture surfaces.
For anyone shipping on that stack, the reframe is about provenance rather than optics. LLaMA arrived in 2023, the assistant in 2025, and Muse this year as another step toward systems drawing on data from across the ecosystem [11]. Ecosystem is the operative word: unified infrastructure across the messaging and social apps [6] means the corpus is not partitioned the way a data-processing agreement tends to assume. If your product sits on a model whose behavioural inputs include third parties who were never asked, the lawful basis you are leaning on is Meta's, asserted about collection you cannot inspect. Meta's position, as the article describes it, is that laws limit what it can collect and users can sometimes opt out, while vast quantities of data remain available anyway [4].
The backlash tells you the shape of the objection you will inherit. Critics have renamed the glasses "pervert glasses" [1] because of what wearers do with them, and what wearers do with them is what produces the data the agent roadmap requires [3]. A public-relations problem gets quieter as novelty wears off. A supply problem does not, because here the objectionable capture is the supply, and the same devices also carry EMG Neural Band signals into the same pipeline [3].
