Why I’m excited (and a little uneasy) about Android Halo’s always-on AI

Every sci-fi movie I’ve ever seen has pointed at an agentic future. Instead of single-purpose bots, a singular voice assistant that can handle everything you throw at it is the future we’ve been shown. And now, it’s coming.

More importantly, it’s coming to the smartphone in your pocket. The future shown let’s me imagine a scenario where, instead of pulling deadlines or data for a slide deck, I can just ask an agent to do that. But not just that — I can ask it to pull that data, compile an email, and send it on my behalf.

This is the promise of Google’s newly unveiled Gemini Spark and Android Halo initiatives, announced at Google I/O 2026. The enthusiast in me is excited. The journalist in me can’t shake a growing sense of unease.

For the last few years, mobile AI has felt like a glorified search engine that we have to constantly babysit. Now, Google wants to transition us into an era of proactive and productive agentic AI that completes tasks on our behalf, in the background, without user interaction. All of that sounds great and the enthusiast in me is incredibly excited about not just the sheer productivity leap this represents, but also the fact that I’m seeing science fiction come to reality in my own lifetime.

But the journalist in me cannot shake a growing sense of unease about what this means for our privacy and the control we have over our devices.
