Machines are even better then that, they generate digital data which unlocks all sorts of possibilities. Amazon could not care less if they lost $1,000,000,0 in stock if they had the data to back that up (sensor data, images, video), which is worth that much to optimize their systems and become a 'leader' which can make money itself. It's why they want to sell data gathering devices so cheaply, cameras, smart assistants, prime, anything that gives them information they can use for AI is a money maker to them. Even if a machine is terrible and useless, you can collect that useless information/data and use it as a data point for other machines that are perhaps not so terrible, any data point is useful afterall. Machines are the future for that reason alone.
