In 20 years, AI will be able to measure and improve human health as well as help us have more happy moments. The magic of AI rests in its uncanny ability to optimize a given goal in a specific way for each person. AI trains "neural networks" on huge amounts of labeled data; then they use what they've "learned" to mathematically pick out and recognize incredibly subtle patterns within other mountains of data, to maximize the given goal. What if we could use the magic of AI to make us healthy or happy? This is quite doable in the next twenty years, and one of the key points I explore in my new book, AI 2041.

If you were the kind of kid who dreamed about living like the Jetsons, we've got some good news for you. Though machine maids and butlers with human-like intelligence still sound like something from a sci-fi movie, AI has become part of your daily experience. It's that helpful website chatbot that asks if you need any assistance. It helps Amazon curate your recommended book list, and Netflix uses it to suggest your next binge-worthy t.v. Your smartphone camera uses it to capture that picture-perfect sunset.
