1. Make easy phone calls
We call them smartphones, but I know a few millennials who don’t ever make calls. They text all day, and when they do place a phone call, it’s maybe once per week. In the living room, if you could make a quick call, it would save time. “Hey Siri, find an appliance repairman and make the call,” would be much faster than using Google Chrome or scrolling through contacts. Today, that doesn’t really work on an iPhone, so the speaker would have to use added intelligence to parse out what you want to do.
2. Engage in real dialog
Siri is pretty dumb, actually. The voicebot doesn’t really engage with you, and the best bot we have for dialog is the Assistant on Google Home. You can ask a question like “Who is Steph Curry?” and then say “When was he born?” and that works. It doesn’t work with Echo or Siri today. Apple could go much further with the speaker and let it converse with you about a wide range of topics; that's important since the speaker will become such an important part of your day (and your morning and your evening).
