Dyson 将 AI 相机装进 $499 的 CameraJet 牙刷

PLUS: Apple enters its John Ternus era

Good morning, tech enthusiasts. Dyson’s latest reinvention of an everyday object is a toothbrush with a camera, AI, and a $499 price tag.

The CameraJet watches the inside of your mouth and brushes, flosses, and rinses in a single pass. Six years and 470K training images later, brushing your teeth apparently requires a tech stack. Also today: Apple enters the John Ternus era, Instagram cracks down on AI people, and Big Pharma finds its next GLP-1-sized opportunity.

In today’s tech rundown:

The humble toothbrush gets an AI makeover

Tim Cook is out, Phil Schiller steps back

Instagram cracks down on AI personas

Big Pharma is coming for baldness

The Rundown: Dyson just entered oral care with the $499 CameraJet, a Wi-Fi-connected electric toothbrush that uses an AI-powered camera to find gaps between your teeth and blast them with a mouthrise while you brush.

The details:

A tiny 100K-pixel camera beneath the brush head analyzes 28 images per second, with a machine-learning system detecting gaps and triggering a jet spray.

Dyson says the system was trained on 470K dental images and runs on 16M lines of code, while its jet is designed to clear plaque away at low pressure.

Users can livestream the camera feed to the MyDyson app, see brushing coverage, and get technique feedback; Dyson says images aren’t recorded.

The $499 package includes a three-second refill/charging dock and launches today in blue and pink.

Why it matters: From vacuums to hair dryers, Dyson built its brand by turning household gadgets into engineering-heavy luxury, and now the toothbrush gets the same treatment. Whether consumers will buy into the ecosystem remains to be seen: its camera works best with low-foaming dental products, which Dyson also sells.

The Rundown: Tim Cook’s final day as Apple CEO came with a second exit: Phil Schiller giving up the App Store and Apple events after more than a decade running both.

The details:

Cook, CEO since 2011, becomes executive chairman of the board, with John Ternus, SVP of hardware engineering since 2021, taking the job Sept.1.

Schiller’s App Store portfolio moves to Eddy Cue’s services division. Cue ran it until 2015, when it went to Schiller and marketing.

Schiller stays an Apple Fellow working on unspecified initiatives, but Bloomberg reports employees read the handoff as a step toward retirement.

Apple seems to be cycling through its old guard, including departures of former COO Jeff Williams, AI chief John Giannandrea, and policy chief Lisa Jackson.

Why it matters: Cook hands over a company worth around $4.6T, up from about $350B when he took the job in 2011 — Apple briefly became the second company ever to touch $5T on July 28, a day after passing Nvidia. Ternus’s first keynote is Sept. 9, covering new iPhone hardware and the redesigned Siri, built on Gemini models.

The Rundown: Instagram is now making AI personas identify themselves: accounts featuring an AI-generated human must toggle on a disclosure label, or they’ll stop showing up in Reels and Explore for anyone who doesn’t already follow them.

The details:

Instagram is renaming its existing “AI creator” tag to “AI-generated profile,” meant for accounts whose central persona was generated or mostly created with AI.

Accounts that should carry the label but don’t can have their reach limited, keeping their posts out of Explore and Reels recommendations for non-followers.

AI influencers that are properly disclosed won’t be penalized; Instagram is targeting the deception, not banning virtual personalities outright.

The move follows backlash over an Instagram AI tool that used people’s public photos to generate their likenesses without explicit opt-in; Meta later pulled it.

Why it matters: A Wired investigation this year found more than two dozen accounts featuring AI influencers promoting the dating app Goose, and the NYT counted hundreds of AI-generated wellness personalities pushing supplements in July. The disclosure rule follows Meta’s $18B settlement over social media harms to children.

The Rundown: Hair loss is turning into a serious biotech race, with AbbVie, Lilly-backed Absci, Veradermics, and Cosmo advancing everything from immune-targeting pills to AI-designed antibodies after decades with little innovation.

The details:

AbbVie’s Rinvoq won EU approval for severe alopecia areata after Phase 3 trials found up to 55% of patients achieved at least 80% hair coverage in 24 weeks.

Cosmo is nearing the finish line with its topical clascoterone: a 1,465-patient Phase 3 program showed continued hair gains through 12 months.

Veradermics is taking another route with VDPHL01, an extended-release oral version of minoxidil now in Phase 3.

Then there’s Absci’s ABS-201, an AI-designed antibody targeting the prolactin receptor that could eventually require only a few injections every six months.

Why it matters: Hair-loss medicine has spent decades dominated by minoxidil, finasteride, and transplants, but now drugmakers are attacking the biology from multiple directions, from immune pathways and androgen receptors to long-acting antibodies. Wall Street sees similarities to the GLP-1 boom, Fortune reports.
