Dyson unveiled their "CameraJet" toothbrush.

It is a toothbrush with "AI" (???) which has a bunch of cameras on it. These cameras monitor your brushing habits and livestream the inside of your mouth to the Dyson app on your phone, basically allowing you to perform an endoscopy on yourself.

Dyson claims the AI within the toothbrush was developed using 16,000,000 lines of code and also them performing AI analysis on 470,000 dental images they've collected over the past 6 years. In other words, Dyson somehow collects about 213+- dental records a day (???).

Dyson claims the AI on the toothbrush isn't stored on the cloud, and it only livestreams to you. This is probably true. However, when you purchasing the toothbrush you must register with Dyson (from their website, or the Dyson app on your cellphone).

Here is what Dyson CameraJet does collect:
- Full name
- E-mail address
- Country, region
- Dyson product
- WiFi information
- Bluetooth (local-network access, device discovery)
- Location permissions (GPS)
- Home and Device information

Dyson, based off of their own privacy policy, collects your GPS location and correlates it with local outdoor air-quality and weather. It may also use this in conjunction with local-network access device discovery to enumerate potential air purifiers, fans, or robotic cleaners. Furthermore, the Dyson app requests labeling where your Dyson CameraJet is located in the house (Master Bathroom, Basement Bathroom, etc).
