Or, take a look at Apple Music's recommendation system in comparison to Spotify's discover weekly.
Now, take a look at Amazon and Google. They both have their own cloud infrastructure (which ironically Apple uses) with machine learning built right into it. Both have state of the art image recognition systems (proprietary) for various applications (Eg. Google Image search, Amazon shopping, etc.)
I am not saying Apple can't do it, I just think they're lagging behind and this move totally makes sense.
