With ChatGPT Codex connected to GitHub it's pretty neat. From my phone I throw some tasks at it and go about my day and then check in with it later. After giving it some time, I come back and look at what it's done and kick off some more or look at diffs and create PRs right from my phone. It's fairly limited in what can be done from the phone so you'll need to have a laptop for anything more involved than eg spelling errors, but it's a very interesting view of the future.
