Yuchen Jin says AI agents are replacing terminals as the coding interface

Yuchen Jin argues that terminals, built around files, commands, and processes, are giving way to AI agents where users state intent and the agent operates the machine. He says understanding Linux and systems fundamentals remains valuable as a moat.

In a follow-up, he calls the terminal era over for coding agents, saying persistent context matters more than tabs, and names the Codex desktop app as the best agentic UI for now.
