Every year, tech companies tell us the same story in slightly different ways. Usually, companies boast things like, ‘This time, life will be easier’ or ‘Your phone will start thinking ahead’ or promise that ‘your device will stop being a tool and start becoming an assistant.’ But no matter how great it sounds, it rarely feels that simple. Google recently wrapped up one of its biggest annual events, Google I/O 2026. While the tech giant made a plethora of announcements, the one that caught my attention was Google Spark. Google positioned it as an AI agent that promises to take over tasks in the background.
The Mountain View-based tech giant marketed Spark as a tool that can plan events, follow up with people, organise information across services, and keep track of things while you focus elsewhere. And yes, in the demo, the tool looked almost magical.
However, once the excitement of imagining it in real-world use wore off, I found myself thinking less about what Spark can do and more about what it needs access to in order to do it. Because there is a difference between using software and inviting software deeper into your life. It also made me think about how, with each passing year, especially since the rise of AI, that line has become blurrier than ever.
Spark is being pitched as an AI assistant that can work seamlessly across Google’s ecosystem. Google says it will only access your data if you give it permission. On the surface, that sounds reasonable until you stop and think about what that permission actually unlocks.
Most of us already use Google services daily without thinking twice. We dump ideas into Google Keep, navigate with Google Maps, schedule our lives in Calendar, and store years of conversations in Gmail. But the real issue is not each service on its own. It is what happens when all of them are connected.
Your calendar reveals where you go and when, while Gmail reveals who matters to you. Your Docs contain your personal and professional thinking, while Sheets expose how you work and organise information. And then there is Maps, with its built-in timeline showing where your life happens.
Separately, they are just apps. Together, they become something far more powerful: a near-complete behavioural profile of you. And Spark appears designed to connect all of those dots into a single intelligent system.
That is where the concern begins. Not because Google is necessarily planning to misuse data tomorrow morning, but because centralising this much personal context in one AI assistant creates an unprecedented level of visibility into people’s lives. And that deserves far more public discussion than it is currently getting.

The hardest privacy conversations are not about obvious tradeoffs. Nobody would simply choose ‘Allow access to everything’ if the benefit were unclear. The reason these products succeed is because they are genuinely useful.
Think about asking Spark to organise a family event. The assistant could send invitations, track responses, update your spreadsheet, create reminders, suggest shopping lists, and even place orders.
It sounds incredible. But now imagine the information it would need to complete all of that: names, emails, schedules, purchase preferences, locations, and payment flows.
Convenience has a funny way of making us stop asking questions. We trade small pieces of privacy repeatedly because each individual trade feels reasonable. Until one day, we realise that our virtual assistant knows our schedule better than we do.
Among the many things announced at this year’s Google I/O, one phrase stood out to me more than anything else. While introducing the assistant, company executives said that ‘Spark can continue working in the background.’ The sentence sounds futuristic but it also sounds slightly uncomfortable.
Google says users will remain in control and Spark will not act on its own. But there is still something psychologically different about software that feels persistent.
When I open Gmail, I know I am using the app. But when an AI agent starts connecting Gmail with Calendar and Docs while I am not actively thinking about it, the relationship changes.
Even if the AI behaves exactly as intended, it becomes less obvious where one app ends and another begins. And that makes it harder for users to understand what information is moving where, not because anyone is hiding it, but because the complexity itself becomes difficult to track.
Whenever privacy comes up, people immediately jump to hackers. I agree that large data pools naturally attract attention. If enormous amounts of personal information are stored centrally, that obviously becomes a valuable target.
The concern is real, but strangely, I do not think that is the biggest issue here. Google deserves credit where it is due. The company has historically maintained a relatively strong security reputation compared with many large internet platforms. We have not seen the same kind of repeated public narrative around large-scale personal data exposure that shaped conversations around some competitors.
So I do not think the conversation should begin with ‘What if Google gets hacked?’ The more interesting question is ‘What happens if Google simply becomes too important?’
This is not a random hypothetical. If Spark succeeds and we all get hooked on an agentic lifestyle where a single prompt makes everything fall into place, then Google would not just host our information. It would actively understand the relationships between pieces of information. And that represents a very different level of influence, especially over people’s personal lives.

After thinking about Spark, I do not think my concern is actually trust. Nor do I think Google is secretly waiting to misuse my information. And I do think the company deserves credit for investing heavily in security and making many of these features opt-in.
But trust is not the same thing as boundaries. The concern I keep coming back to is simpler: do we want one company becoming increasingly aware of how our digital lives connect together?
For some people, the answer might be yes because the time savings will be worth it. For others, the answer may be no, and that is fine too.
Because the real conversation is not whether AI assistants should exist. It is about where each of us draws the line between helpful and too helpful.
Spark might end up becoming one of the most useful AI tools we have seen. I just hope that while companies build assistants that understand us better, they also leave us enough space to remain a little mysterious.
