Autonomous commerce (aCommerce) gives money — and the ability to spend and earn it — to machines. It is to artificial intelligence what electronic commerce was to PCs, and mobile commerce to smartphones. Like previous digital waves, aCommerce is tiny now, but will transform industry and the economy by making transactions frictionless. aCommerce will capture both financial and non-financial values, like CO2 footprint, to mitigate environmental and social costs of today's economic system. It will unlock latent industrial capacity, unused goods and machines, and food, water, and energy - literally creating abundance from what we waste today. It will integrate distributed ledgers, predictive analytics, low-power networks, edge AI, and other technologies; leading to legal personhood for machines.
