ML for improving business seems to be an overkill. As in, if you are a regular business, the best I can guess is developing better pattern matching systems, say credit card fraud. Most businesses I see, are using AL/ML for improving their current processes.

However, AI/ML is definitely opening up new areas of business, such as autonomous robots (A roomba is much better at its job with a ML component in it, without which, it would have been difficult to come up with such a device), Social media, face recognition, etc.

All in all, most of AI/ML needs are centered around pattern matching in one form or the other. There is much less AI, a lot more Pattern Matching.
