Google has announced that it will discontinue Google Assistant on Android and Wear OS devices starting September 4, 2026. The AI-powered successor, Gemini, will take over on smartphones, tablets, watches, and in cars with Android Auto. Gemini is a probability-based large language model, which may face a challenge in replicating the reliability of its deterministic predecessor for everyday commands. The transition marks a significant shift in Google's AI strategy. This development matters as it will impact the functionality and user experience of Google's devices and services.
