This is a long but amazing read about building decentralized artificial intelligence networks by Ali Yahya from A16Z. This model of incentivized coordination of individuals on a global scale is the foundational strength of decentralized networks and a window into the structure of the 21st century.
TLDR: AI is centralized inside big institutions like Google and is impossible for startups to improve upon. You need extremely detailed and deep data for models which is hard to find and expensive to buy. Ethereum allows for tokenized incentivization for people to collaborate by adding data and improve the models by earning a stake in the project with their contribution. Creating a data and usage market for these models allows for bigger and more accurate data than any one centralized manager can achieve. Oh, and other developers can use it to build their own products in a self-fulfilling cycle.
This is the fundamental superpower of Ethereum and decentralized networks. Everyone collaborates and composability allows for infinite complexity to be layered on top inexpensively.
