Gemini Spark becomes a 24/7 cloud agent

Google launched Gemini Spark in Australia as a 24/7 personal cloud agent that can keep working when a laptop is closed or a phone is locked, with rollout to AI Pro subscribers over the next few weeks. The official launch post says the Gemini 3.5-powered service connects to Gmail, Docs, and Sheets without setup, runs recurring tasks, and asks before high-stakes actions such as sending email or spending money. For builders watching ChatGPT erase the handoff between conversation and background work, the signal is that persistent execution and explicit approval gates are becoming baseline consumer-agent features rather than enterprise-only plumbing.
