What I'm curious is why there's not yet a marketplace for consumer-generated data. Thinking things like wearables. Is it that these wearables are too miserly over their data, or are there other considerations that make this more difficult than some of the more common ones I've seen such as e-commerce and supply chain.
I see examples for medical data in this thread, which is notoriously slow to "open," so I'm curious what the reasoning may be...
