No independent test. And the hardware is pre-production, shipping target early 2027."},{"host":"Chris","text":"Even half that beats my typing. Hands-free, silent input is a real category."},{"host":"Matilda","text":"The post goes further. Quote: \"two people could have an entire conversation while barely moving their mouths.\""},{"host":"Chris","text":"That part is pitch-deck fantasy. Full stop."},{"host":"Matilda","text":"It's not just fantasy, it's the pitch! The product doesn't exist yet."},{"host":"Chris","text":"That's how hardware startups work—"},{"host":"Matilda","text":"No, no, wait. Two hundred words per minute is a performance claim with zero independent verification."},{"host":"Chris","text":"So flag it, which you did. But YC doesn't back a nothing idea."},{"host":"Matilda","text":"They back an early bet. One point three million isn't a hundred million."},{"host":"Chris","text":"The use case is strong. You can dictate an email without anyone hearing. Train, meeting, hospital."},{"host":"Matilda","text":"We already have throat mics and bone conduction. Why glasses?"},{"host":"Chris","text":"Because glasses are already on your face. One less gadget."},{"host":"Matilda","text":"Unless you don't wear glasses. Then it's a weird camera you strap on to mouth words."},{"host":"Chris","text":"That's why early buyers will be people who need silent communication, not you."},{"host":"Matilda","text":"So who exactly? Commuters? Call centers?"},{"host":"Chris","text":"Doctors charting notes without waking a patient. Pilots. Noisy factory floors."},{"host":"Matilda","text":"Now those are better than two people on a date mouthing at each other."},{"host":"Chris","text":"No one said date night."},{"host":"Matilda","text":"The post said entire conversation. I'm taking it literally."},{"host":"Chris","text":"And I'm taking the useful version: quiet command input."},{"host":"Matilda","text":"Then sell that, not the telepathy fantasy."},{"host":"Chris","text":"They kind of did. Both."},{"host":"Matilda","text":"Fine. I'll wait for the demo."},{"host":"Chris","text":"No one's taking pre-orders, Matilda."},{"host":"Matilda","text":"Not yet.

The trades are a huge market for this."},{"host":"Matilda","text":"Here's my problem. A bot answering the phone doesn't know a dripping faucet from a flooded basement unless someone builds that in."},{"host":"Chris","text":"That's exactly why you hire a former plumbing owner as COO! She knows the difference."},{"host":"Matilda","text":"Then she'd better review every call, because one wrong quote and the customer is gone."},{"host":"Chris","text":"You train the agent on the company's own estimates and escalation rules. It's filling out a form."},{"host":"Matilda","text":"And if a customer calls panicking and the bot asks for an account number, they hang up."},{"host":"Chris","text":"Then the owner gets an angry call. That already happens with voicemail."},{"host":"Matilda","text":"No, with voicemail they hear a human or a clear callback. This is a bot pretending to be the office."},{"host":"Chris","text":"You're holding AI to a higher bar than the average overworked front desk."},{"host":"Matilda","text":"Because the average front desk didn't, according to that post, raise fifty-two million from Khosla Ventures."},{"host":"Chris","text":"That's ... actually fair."},{"host":"Matilda","text":"I'm not anti-automation.

We disagree on whether a language model can handle emergencies."},{"host":"Matilda","text":"I'll take the human for the burst pipe. The bot gets routine bookings."},{"host":"Chris","text":"Apparently, per that post, Broccoli got the funding, so somebody's buying that split."}]}
