They definitely have incorporated their impressive papers into their search engine. They've integrated BERT, a state of the art transformer model, into search engine, and it is used for almost every query now [1].
Google also has best-in-class computational photography (for their phones) and the best voice assistant, which is all ML.
I've been wondering about the voice assistant, which I find absolutely appalling. It's so bad (and it's gotten worse) that my children noticed it and make fun of it! I don't understand why anyone would want to use it. In contrast siri works quite well, so I assume it's not because of the way I speak.
