In the Battle Between Amazon and Google, It's Not the Hardware That Will Win the Game

To start off, I don't think the battle between Amazon Echo and Google Home is as important as the one between Amazon Alexa, which is their voice assistance service, and the Google (Voice) Assistant. Both Amazon Echo and Google Home are speakers with voice assistance built into them. The speakers are fairly standard, as speakers go. The real magic happens in the voice assistants that sit in the cloud and do the heavy lifting on behalf of these devices. You can expect that, in the future, most of the devices you own will have voice assistance built into them.
