🔮 What's Coming: Agents, Not Just Assistants
The most important 2026 trend isn't any single tool — it's the shift from assistant to agent:
- Cursor Background Agent: runs autonomous multi-step tasks while you focus elsewhere
- GitHub Copilot Workspace: takes an issue, plans a solution, implements it, creates a PR
- Devin (Cognition): full end-to-end engineering tasks with minimal human input
- OpenHands (former OpenDevin): open-source agent that browses docs, writes code, runs tests
We're entering the era where AI doesn't just suggest code — it builds software.
