In order for a virtual helpmate to run your life, it needs to engage with the providers of all the services you rely on, from your calendar app to your Uber ride. Those providers must either partner with the company operating the assistant, or design their app to integrate with the assistant. So Spotify will stream music upon request via Alexa, and Honeywell’s smart-home thermostat, via Assistant, will bump up the temperature 15 minutes before Grandma’s expected arrival.

For providers, “if there is a competitive advantage to be gained, then absolutely they will do it,” said Parks Associates.
