The Dawn of Always-On AI: How Harvard Dropouts Are Pushing the Boundaries of Smart Glasses and Privacy

In a bold move that blends cutting-edge artificial intelligence with wearable technology, two former Harvard students are poised to launch what could be one of the most controversial tech products of 2025. AnhPhu Nguyen and Caine Ardayfio, co-founders of startup Halo, have created a pair of AI-powered smart glasses called Halo X that continuously listen to, record, and transcribe every conversation the wearer has, promising to give users what they describe as “infinite memory” and “super intelligence.” Priced at $249 and available for preorder, these glasses represent a significant leap in wearable AI technology—but they also raise profound questions about privacy, consent, and the normalization of surveillance in our daily lives.

The concept behind Halo X is deceptively simple yet technologically complex. Unlike conventional smart glasses that require manual activation, these devices are designed to operate in an “always-on” mode, constantly processing audio from the wearer’s environment. “Our goal is to make glasses that make you super intelligent the moment you put them on,” explains Nguyen. The glasses not only record conversations but employ sophisticated AI to analyze them in real-time, displaying relevant information directly in the wearer’s field of vision. If someone asks a complex question like “What’s 37 to the third power?” or uses unfamiliar terminology, the answer appears instantly on the glasses’ display, creating what Ardayfio describes as an experience similar to “IRL [in real life] Cluely,” referencing the controversial startup that helps users “cheat” in various scenarios from job interviews to exams.

The technical implementation of Halo X represents a balancing act between form factor and functionality. While the glasses themselves have a microphone and display, they lack onboard processing power for intensive AI operations. Instead, they connect to a smartphone app that handles the heavy computational lifting. Under the hood, the glasses leverage Google’s Gemini for reasoning and mathematical tasks, while Perplexity powers their web-searching capabilities. Audio transcription is managed by Soniox, which the founders claim never stores recordings. This distributed processing approach allows the glasses to maintain a discreet, conventional appearance while still delivering advanced AI functionality.

What makes Halo X particularly controversial is its deliberate lack of external indicators that would alert others when recording is taking place. Unlike Meta’s Ray-Ban smart glasses, which feature an indicator light when their cameras and microphones are active, Halo X offers no such transparency. “For the hardware we’re making, we want it to be discreet, like normal glasses,” Ardayfio told TechCrunch. This design decision places the burden of disclosure entirely on the wearer, raising serious ethical and legal concerns about covert recording.

Privacy advocates have been quick to sound the alarm about the implications of normalizing such technology. Eva Galperin, director of cybersecurity at the Electronic Frontier Foundation, points out that while small recording devices aren’t new, “normalizing the use of an always-on recording device, which in many circumstances would require the user to get the consent of everyone within recording distance, eats away at the expectation of privacy we have for our conversations in all kinds of spaces.” This concern is particularly relevant in the twelve U.S. states with “two-party consent” laws, which make it illegal to record conversations without the agreement of all participants.

The founders acknowledge these legal complications but maintain that compliance is the user’s responsibility. “We trust our users to get consent if they are in a two-party consent state,” says Ardayfio. This hands-off approach to legal compliance places considerable onus on consumers who may not be familiar with the complex patchwork of recording laws across different jurisdictions. Moreover, it raises questions about whether technology companies have a responsibility to design products that encourage or enforce ethical use, rather than simply enabling potentially problematic behaviors.

Data security represents another significant concern. While Nguyen claims the finished product will be end-to-end encrypted, the company has provided limited details about implementation. The founders have expressed their intention to obtain SOC 2 compliance, an independent security audit that verifies adequate protection of customer data, but have not committed to a specific timeline. In an era of frequent data breaches and growing privacy concerns, these assurances may not suffice for many potential users or privacy advocates.

This isn’t the first time Ardayfio and Nguyen have pushed technological boundaries in ways that raise privacy concerns. While still at Harvard, the duo developed I-XRAY, a demonstration project that added facial recognition capabilities to Meta’s Ray-Ban smart glasses. In testing this technology, they scanned random passersby without consent, showing how easily personal information could be accessed through such devices. In a striking moment of candor during an interview with 404 Media, they acknowledged the potential dangers, with Nguyen noting that “Some dude could just find some girl’s home address on the train and just follow them home.”

The market for smart glasses has grown increasingly competitive, with established players like Meta and Apple investing heavily in the space. Meta’s Ray-Ban smart glasses have gained popularity as a relatively restrained entry in the category, balancing functionality with privacy considerations through features like recording indicator lights. Meanwhile, Apple’s Vision Pro represents a more immersive approach to augmented reality, though at a significantly higher price point and with different use cases. Halo X positions itself as offering capabilities that larger companies might hesitate to implement due to reputational concerns.

“Meta doesn’t have a great reputation for caring about user privacy, and for them to release something that’s always there with you — which obviously brings a ton of utility — is just a huge reputational risk for them that they probably won’t take before a startup does it at scale first,” Nguyen told TechCrunch. This statement highlights how smaller companies with less brand equity at stake can sometimes move more aggressively into controversial technological territory.

Looking beyond the immediate privacy concerns, the emergence of always-on AI glasses raises profound questions about how such technology might reshape social interactions and cognitive processes. Will people become dependent on external AI for information recall and decision-making? How might constant recording affect the authenticity and spontaneity of human conversations? These sociological implications remain largely unexplored as the technology races ahead of our collective understanding of its potential impacts.

The Halo X glasses represent a fascinating inflection point in wearable technology—a moment where technical capability has outpaced both regulatory frameworks and social norms. As AI-powered devices become increasingly integrated into our daily lives, society faces the challenge of establishing appropriate boundaries and expectations. The success or failure of products like Halo X will likely influence how future generations of AI wearables balance utility with privacy, and whether consumers prioritize convenience over confidentiality in their technological choices.

As these glasses prepare to enter the market, potential users should carefully consider not only the promised benefits but also the broader implications of adopting always-on recording technology. Beyond legal compliance, there are important questions of ethics, social responsibility, and the kind of technological future we wish to create. The debate surrounding Halo X reflects a larger conversation about AI’s role in society—one that will continue to evolve as these technologies become increasingly powerful and pervasive.
