i love that the codex team releasing codex cloud, codex cli, codex ide, and codex review all in ~3 months is a self-contained proof of how effective the tools are.

OpenAI nailed it with Codex for devs ?!. I've been using GPT-5-high in Codex for a few days and I don't miss Claude Code. The value you get for 20 a month is insane. The PR review feature (just mention @ codex on a PR) is super easy to set up and works well.

What makes programming so fun is leverage. One person, no overhead, massive output. AI takes that up another level—and makes it accessible to everyone.

Sure — ChatGPT helps with coding and research, but maybe the real treasure was the em-dashes we learned to use along the way.
