With coding agents AI almost never manually type code anymore. It would be great to have a code editor that runs on my phone so I can do voice prompts and let the coding agents type stuff for me.
To be fair with the languages I use there are only a finite number of ways a particular line or even function can be implemented due to high level algebraic data structures and strict type checking. Business logic is encoded as data requirements, which is encoded into types, which is enforced by the type checker. Even a non-AI based system can technically be made to fill in the code, but AI system allows this to sort of be generalized across many languages that did not implement auto-complete.
I have been doing this with GitHub's copilot agent web interface on my phone; word-vomit voice prompt + instructions to always run the tests or take screenshots so I can evaluate the change works really well.
