> Machine learning is used to help the iPad's software distinguish between a user accidentally pressing their palm against the screen while drawing with the Apple Pencil, and an intentional press meant to provide an input. It's used to monitor users' usage habits to optimize device battery life and charging, both to improve the time users can spend between charges and to protect the battery's longterm viability. It's used to make app recommendations. The problem with machine learning altering the behavior of a device is it shortcuts human learning. The human brain is very good at learning deep insights about things and its environment and alters its behavior accordingly. If things change while we're learning about them, it confuses and upsets us. A dumb machine is much easier to use than a "smart" one.
