That's a terrible take considering how much money both governments and insurance companies would save. There are a ton of studies made on injury prevention every year. I've personally participated in one study for 19 years now. Exercise is one of the best methods to prevent it and it would be a very bold claim to say there's no money in fitness. The issue with accelerometers is that they don't prevent fall, only notify afterwards, and you get a ton of false positives. To the degree that Apple devices are becoming a real issue for health personnel.
