Interesting article about a fascinating part of our future. I think that most current consumer wearables provide value through reliable information, not necessarily accurate information, with the exception of GPS. I think this will definitely change over the coming decade as the hardware and software improves. I've recently become interested in the usage of blockchain technology to store this data, instead of centralised servers maintained by the company. At the moment, the primary benefits are privacy and the ability to control ones own data, instead of it belonging to the company. My understanding of this area is only in it's infancy, but I'd be interested to know your thoughts on the use of blockchain in this area?
