Emacs originated in the era of time-sharing systems and ed (the precursor of vi) is particularly handy over slow network connections. Even when coding remotely, Emacs and vi are the tools I reach for.

We write prompts, launch agents and review what they produce.

What better tool to review that output than the one you know really well? For me and many others, that's Emacs and vi.
