Another me-too from Google. It doesn't matter how much money they put on it, it won't work until they do something innovative. Apple had to do it to get where they are.
Apple aquired a lot of companies to get their "innovative" features. Siri was aquired (I know, its not great, but it was novel when it came out), PA-Semi was aquired (boosted their in house SoC development), and the original Kinect team for the iPhone X face recognition sensor suite come to mind.
