Google Home was a decent first stab at taking on Amazon's Echo, but there's clearly room for improvement. Today at during the opening-day I/O keynote, the company revealed that its smart speaker will soon be able to give you proactive notifications, like alerting you to traffic delays ahead of upcoming appointments. Google Home will light up to let you know it has an alert for you, so it thankfully won't just start talking without any prompting. Additionally, you'll soon be able to see visual responses to your Home queries on all of your devices. So, for example, if you ask for directions somewhere, you'll get that routed straight to your phone.
