Lots of scepticism here, but I think this may really take off. After 25 years of heavy CLI use, lately I've found myself using codex (in terminal) for terminal tasks I've previously done using CLI commands. If someone manages to make a robust GUI version of this for normies, people will lap it up. People don't want to juggle applications, we want computers to do what we want/need them to do.
Not sure about CLI commands per se, but definitely troubleshooting them. Docker-compose files in particular..."here's the error, here's the compose, help" is just magic
