I told my engineers to delete their IDEs - PyCharm, VS Code, Cursor. Replace them with Claude Code and Claude Cowork in a terminal. The result was a dramatic productivity leap.

Features shipped in hours instead of days. This wasn't marginal; it was a step function improvement. Other founders report similar gains, visible in cleaner commit histories.

The team's initial shock centered on control, oversight, and code review. But the core question was wrong: why manually review every line an agent writes? The solution lies in better tests, CI pipelines, and clear requirements. Build guardrails, not line-by-line inspection.

While I haven't forced everyone yet, I will - especially as I build Lanes with this mindset. Coding, as Boris Cherny confirmed, is practically solved for. Yet the terminal-only workflow has cracks: managing 5-10 agents leads to context loss and coordination battles.

Your brain becomes the bottleneck. Lanes aims to solve this by managing context. The shift extends beyond code: integrating Linear, Slack, and docs into one flow creates invincibility.

Why juggle separate windows when one flow suffices? The IDE's world is ending. The ADE - Agentic Development Environment - is here.
