Long before it was ML it was called data mining. The textbook example is Walmart discovered that men buying diapers rewarded themselves with beer so Walmart created endcaps with beer and diapers. What the textbook didn't say is whether the cost in millions putting the data warehouse together ever was matched by the extra money made putting beer with diapers. Data mining was a fad long before ML co-opted its throne. A human eyeballing data has a better chance of finding these kind of new trends. Where ML weighs in us with fine tuning known trends such as with auto pilot, voice recognition, facial recognition, etc. Even then ML is only as good as the things being tuned.
