The $500 Dyson CameraJet (AI water jet toothbrush with an integrated camera) is, apparently, an abject failure, with liquids leaking into the interior and shorting out the circuits.
Daftest. Timeline. Ever.

@david_chisnall @hrbrmstr I think that you are missing the point to have recurring fees from customers. Which company could provide the "best" toothpaste but the brexit company euh I wanted to say the company which made that?
I strongly suspect that, if it's successful, companies that already have production and supply chain infrastructure for toothpaste will sell transparent toothpaste for the device at less than Dyson can sell it for. Until that point, it's just a barrier to adoption. The kind of person who cares enough about their teeth to spend $500 on a toothbrush almost certainly has opinions about toothpaste.
Amusingly, there was another company a few years ago that made a whole-mouth toothbrush that was made from a cast of your teeth and allowed 20s of chewing on the brush to have the same benefit as two minutes of brushing with a normal brush (and they had some data to back this up). It cost less than the Dyson thing.

My favourite thing: it needs special transparent toothpaste, otherwise the camera can't see anything.
Now, personally, 'works with existing toothpaste' is the kind of thing I wouldn't have bothered putting into a requirements document because it's so obvious, along the lines of 'should not stab user in the eyes'.
