OP is referring to the existence of mature tools like Theano and Torch. If Deep Learning can help, Amazon is already using it internally, possibly with either their own framework, or with one of the other open-source ones. If something will increase revenue or decrease cost, you can be assured there's already an initiative for it. Tensorflow is not adding some magical improvements to Machine Learning, it's just one more framework (from a reputable company). The hard(er) part is getting data, cleaning it, testing, making sure it works in production, and updating as data changes.
