Google Chief Executive Sundar Pichai announced during the October 4 Google Event that they are evolving from a mobile-first world to an "AI-first world". With that evolution, Google is going to be at the forefront.

Google takes credit for designing the phones around Google Assistant, the tech giant's answer to Apple's Siri, Amazon's Alexa and Microsoft's Cortana.

"The idea behind Assistant is that Google wants to build a Google for each person, not just a Google for everyone," Pichai said.

According to Engadget, the company demonstrated the fruit of its efforts earlier this year by giving us a taste of its AI "Assistant" in its Allo messaging app.

However, the Allo chat app was not just enough. According to the Google Chief Executive, "For Assistant to be truly helpful, it needs to be available universally, and so the company today showed how it plans to bring the helper to a wide range of products, including phones and items for your living room."

Assistant offers navigation and points of interest. At the start of the day, Assistant can also run down your list of upcoming activities and reminders, and does so somewhat colloquially.

But to do that, Google is investing heavily in mobile specifically, smartphones. The tech giant introduced two new phones, the 5-inch Pixel and the 5.5-inch Pixel XL, at a San Francisco keynote event.

The new Pixel phones carry branding that identify them as "Phone by Google," which is a departure from the old Nexus "partner" branding but a crucial turn in what the company is trying to do: owning the phones as its own.

One of Google's commitments is that Assistant will get better with time. Seemingly, it's already a solid amalgamation of all of the company's services that you can access from basically anywhere. That is more effective if you have a Pixel phone or Google Home speaker.
