You’re going to have a lot more to talk about with Siri this fall. In iOS 10, Apple Inc.’s upcoming iPhone and iPad operating system, you’ll be able to control third-party app functions using the company’s voice-activated assistant for the first time.

Among the first apps to yield to Siri are big names like WhatsApp, LinkedIn, Pinterest, Square Cash and Slack, along with lesser-known ones including Looklive and The Roll.

I’ve tried out Siri’s new abilities in demos with developers over the past few days. After getting an early look at a more capable Siri, it’s clear that this long-overdue feature is important to making Siri more useful in everyday life. Still, controlling third-party apps is merely a first step toward Siri living up to Apple’s promise as a new way to control our devices.

We are at the cusp of a new age, an age that will see Siri play an ever-increasing role in our lives. Adding a basic ability for Siri to interact with 3rd party apps is foundational. I have no doubt that we’ll see those interactions become more and more sophisticated over time, and more and more valuable as a result.
