BlackRock, Inc. (NYSE: BLK), the world's largest asset manager, is turning to machines to help pick stocks. To many, it may seem the use of machines and artificial intelligence technologies is reserved for companies like BlackRock with trillions of dollars under management. The reality is companies of all sizes are turning toward machines to improve their business. For example, Bloomberg profiled a craft brewery called Deschutes Brewery that uses artificial intelligence technologies to keep track of vital aspects of the beer brewing process. When a batch of beer wasn't fermenting as it should, the machine automatically detected a problem with the temperature, triggered a warning and then took the necessary steps to save the batch.
