General trend today has been, products are introduced first for iOS and then brought into android, depending on the success of the product. So android is always catching up to ios. If Google adopts swift, then products will be available more or less the same time, because the codebase will be the same.
Since Apple open sourced Swift, swift is moving to server side as well. So lot of developers are excited and learning swift. Days are not far when a UI kit will be made for android (swift already compiles for android). If Google adopts swift like it embraced Typescript by MSFT, then it will bring lot of developers into Android platform too.
I see advantages for Google to embrace swift. But hey...I am not Sunder Pitchai (though, I am from the same state).
