James Dyson Unveils $499 CameraJet Toothbrush with AI and Water Jet

Trung Phan posted that James Dyson, who still owns 100 percent of his company, gave a seven-minute presentation on an AI-powered CameraJet. The device uses a 1mm camera with a 100K-pixel macro lens in the brush head to handle brushing and flossing together. Phan noted that people typically brush for 45 seconds instead of the recommended two minutes and called flossing archaic. Other users shared reactions to the $499 price and the addition of a camera. Separate posts compared Dyson's full ownership stake to equity held by founders at other firms.
