An over engineered toothbrush is a dental product just as much as a very cheap one and there are for sure greedy people interested in trying to get people to log their brushing data on a corporate cloud and later link together their insurance and their dental habits at some point and there are for sure people willing to pay for detailed brushing data. It’s just the very beginning of it all still. Give it 20 years, your insurance company or dentist will ask you how come you’re not logging your brushing.
