Proof of age, court of comments
Opening up 'Zero-Knowledge Proof' technology to promote privacy in age assurance
Google says you can prove you’re 18 without oversharing — commenters are already fighting
TLDR: Google open sourced tools that could let sites confirm you’re over 18 without seeing all your personal details, a move tied to Europe’s upcoming digital ID plans. Commenters were split between cheering the privacy angle, mocking the tracker loophole, and arguing that age checks themselves are the real problem.
Google has thrown open the doors to its new privacy toolkit on GitHub, saying it could let people prove they’re old enough for a site without handing over loads of personal data. In plain English: instead of flashing your full digital ID, you’d just prove “yes, I’m over 18.” The company is pitching it as a big win for privacy, especially as Europe prepares new digital ID rules in 2026.
But the real action is in the comments, where the crowd instantly turned this into a mini culture war. One camp basically said, nice idea, but are we pretending trackers don’t exist? One skeptical commenter asked what the point is of sharing less with one site if the same ad companies can still stitch together your activity across the web anyway. Ouch. Another took the debate in a totally different direction: forget the math, should age gates even exist? They argued kids would lose out if the internet gets locked down too hard, with parents needing override powers.
Then came the nerd drama: the privacy purists showed up demanding the gold standard, arguing that not just your age, but also when your proof was issued, who got it, and where you used it should stay hidden. And of course, one deadpan comment simply posted "[2025]", which feels like the internet’s favorite joke format for “we’re all going to be talking about this for a while.” Even the most privacy-friendly announcement couldn’t escape the classic online pile-on: excitement, suspicion, policy panic, and one-liner comedy all at once.
