Ask HN: What has “machine learning” done for YOU?

I've been pretty excited by the various machine learning libraries/frameworks, like TensorFlow, Theano, Keras, Torch, Caffe, etc. I've participated in some of the more basic Kaggle challenges, and I've learned enough about the "how does it work" and "why does it work" (and remember enough of the mathematics from my younger days) that I'm able to teach the basics of simpler aspects, especially related to NLP, like classification or syntax analysis. What I haven't done, however, is come up with a direct answer to the question: "What can machine learning do for ME?" I don't mean, "what can someone else's AI do for me," I really want to know how YOU have used machine learning to solve a problem for YOU. "You" may be a company, or even better, "you" are an individual who set out to answer some personal mystery, and by solving that mystery, done something to improve your quality of life... or even just satisfied a burning curiosity. So, HN: What has machine learning done for you?
