Why Didn’t Google Build Muse?

The useful part

Unlike Meta, Google runs the biggest email service in the world – an email service which contains the most valuable trove of personal information (not to mention communication capabilities) for a personal assistant AI. Sure, Meta has Facebook, Instagram, and WhatsApp, but Muse can't really work without access to any of these Google services. Depending on where you live, it could probably work as a sort of WhatsApp personal assistant AI, but Muse would be a shell of what it currently is – again, thanks to the hooks into Gmail, Google Calendar, etc.

How it works

• Say hello to ' CC ', which is not Gemini Spark, but another agentic product that Google is working on.
• This week, the search giant introduced a new version of CC, an AI agent designed to work across email, calendar, chats, and tasks.
• That's what Muse has nailed here: an interface that guides the user along, unveiling capabilities without bombarding them.
• Gemini is a different story, perhaps rivaling even ChatGPT in terms of active users now.
• It just looks sort of silly given all the tools they control mixed with their relatively strong level of user trust that Meta is eating their lunch here with Muse.

What to take from it

Or maybe it's because they were waiting on Gemini 3.5 Pro, which was promised for June but still has not launched (and seems like it won't be now, as we move towards Gemini 4). Regardless, no one that has responded to my post seems to know Gemini Spark even exists, which is a problem. At a high level, that all sounds fine, perhaps even good – focusing on family use-cases could be an interesting inroads for adoption (which is the single biggest problem that all of these products face).

Details worth keeping

The longer answer is probably more interesting here too. What is probably the biggest calendaring system in the world. They also run the largest search engine in the world.
