Can you think for me, please? The AI behind everyday apps

Below I'm going to talk about two of the most used digital products and how they use AI and machine learning in order to provide the best user experience. So, before we dive into Google's wonder search platform, we have to clear something off, since there's a lot of confusion around this. Most of my friends call it Google suggestions, but it's not the case. Since they integrated AI and machine learning in their search algorithms, those are not suggestions anymore, but predictions. "What's the difference between those two?" you may ask.
