Short answer: Ramses Alcaide calls it an overfit issue: the model assumes anyone with a mustache is an adult. He says brain data can track brain age, and some companies turn two minutes of brain data into a key that can't be replicated.

Sam Nadler [18:35]: Great. And just to wrap up here, guys, just for fun, we thought this was hilarious. Kids are bypassing age verification checks with a fake mustache. Leave it to kids to get past some of those filters. I heard, I think it was today, Facebook announced that they're analyzing bone structure and facial height to understand if the user is a minor, but we thought this was a fun article to end the day.
Ramses Alcaide [19:01]: Yeah, I think it's kind of crazy to think about that's how simple these machine learning models are to a certain degree, that just putting on a fake mustache is enough.
Jordan Metzner [19:10]: Yeah, it reminds me of kind of hot dog not hot dog, right? So the model can just say adult, not adult, right? And then you put the mustache on immediately, it's adult, right?
Ramses Alcaide [19:19]: It's an overfit issue, right? It's like what kid has a mustache? So as long as there's a mustache, the model's like, Oh man, clearly this must be an adult, right? Like no matter how their face looks like, which is kind of crazy to think about.
Jordan Metzner [19:31]: Yeah, I remember there used to be video games to check your age. They would ask you like trivia like kind of that would age you properly, you know? Maybe we'll have to go back to that, but then ChatGPT just solves it again. So you know, I don't know. There's you know, that's why we need a better device to understand, true identity. Tell us more about how your device can tell true age.
Ramses Alcaide [19:53]: Actually, that's a really interesting perspective, which is, so we've captured thousands of people worth of data at this point, and some of it with work with the Department of Defense and tracking the age of people's brain and how much damage, has happened or, the case of a soldier in the field. And so, yeah, I guess that's one way of at least verification. There's also a few companies out there that are doing individual verification. It's really hard to duplicate a person's individual brain signature, and so I've seen a few companies focused on how do we collect two minutes worth of data and then turn that into a key that can't be replicated? That's another way of doing it.
Jordan Metzner [20:32]: Super cool. All right. Well, was really fun episode. Was really great to chat with you. Awesome to learn about your product and obviously just the early days of kind of like, being able to get this feedback. Obviously, people have things like Apple Watches and Oura Rings and Whoop bracelets and things like that, but I think your headset just shows that we're starting to creep into a new area of self analysis that really will allow us to empower us to do cool new things.
Sam Nadler [20:57]: Absolutely. Thanks for joining. I'm a little scared when I eventually get one of your headphones, how distracted I am throughout my typical workday. Maybe I don't I want to
Ramses Alcaide [21:08]: Tell you, Week over week, you'll get better at it. That's and that's why You're getting them. So there you go.
Sam Nadler [21:12]: Thanks for joining.
Ramses Alcaide [21:15]: Honored to be here. Bye, everyone.
