what does it mean for a machine to “learn?” How do we quantify something like skill growth when, for humans, learning is a subjective experience?

You want to have a computer be able to recognize speech. You could take the time to program exactly how all words sound in various voices. Or you could program some basic recognition with a learning algorithm and then feed it a bunch of voices, have it guess, and tell it whether it was right or wrong. Knowing it was right or wrong gets fed back into the recognition so it can learn. A big difference is that machine learning usually has a fudge factor so it can weigh whether a sound is one word or the other based on its learning rather than trying to do a direct match.
