Google search will use AI and Big Data

We have already talked about Big Data and how this is being used by Google search (https://www.appfutura.com/blog/whats-big-data-and-how-to-use-it/) but now I've found an article about AI and Google search. It seems like they will be using it sooner than expected. And it is probable that their main purpose is to help their clients (users) have a greater experience. Do you agree?

Another new technology has been added to the list of technologies incorporated into the Google Search, i.e., Voice Search.
According to the stats shared by Google, 20% of the searches on Google mobile app and Android services are made by voice, and this number is going to increase in the next few years. The marketers also announced that search by voice will replace keyboards by 2022.
These figures are not only staggering for Android users, but also holds a significant importance for mobile app developers.
Wondering how?
