Stuff like this should be great, but all I can think about is how capitalism will ruin it. Will they only make it an “service” available via subscription, and shut off your ability to walk if you don’t pay? Will it require expensive software updates, or only work if you’ve got wi-fi or a cellular connection? What happens to the patients if the company which owns this patented technology goes out of business?
Managing a chronic problem is much more profitable than curing it completely.
