The Convergence of AI and Blockchain: What's the deal?

In the previous section, we quickly touched upon the effects that AI might eventually have on the blockchain. Now instead, we will make the opposite exercise understanding what impact can the blockchain have on the development of machine learning systems. In spite of all the benefits that AI will receive from an interaction with blockchain technologies, I do have one big question with no answer whatsoever. AI was born as in an open-source environment where data was the real moat. With this data democratization (and open-source software) how can we be sure that AI will prosper and will keep being developed?
