Google announced Gemini Spark at I/O 2026 as a 24/7 personal AI agent baked into the Gemini app, cloud-based, Workspace-connected, and running even when you close your laptop.

The product shift is enormous: this is not a chatbot you talk to. It is a background worker you delegate to. The relationship moved from ask and receive to assign and supervise.

The hype is real because this is what turns an assistant into infrastructure - something you stop noticing because it is always already working.

The reality check: a background agent with calendar, email, and file access is only useful if you understand exactly what it can touch, what it will do without asking, and how to make it stop.
