It’s a major payoff of a lot of small research advances made by Google over the last few years. In and of itself it’s not a terribly groundbreaking research result, but a bunch of parallel AI, NLP, and systems research had to go into this to take it from toy experience to what will eventually be a robust service. This is the promise of AI in the 2020s: incremental services that chip away at various low-cognition but high-variance/pattern-based tasks that litter our home and professional lives.
