I’m not really concerned with this, at least not yet. Even with relatively simple prompts, you can get very different results even from the same AI model because the individual responses are not consistent and can vary over time. There is an API parameter called ‘temperature’ that can be used to control this somewhat, though it is not something directly controllable through most chat UI. Further, the more the AI has to guess, the more variable it becomes. I wrote a blog post about AI guessing and how to reduce it. You have to be very detailed and specific to get it to produce the code the way you want it and not how it guesses.
As for licensing of my own apps, they may have to fight over it as I use more than one AI provider to generate different things. They would need to prove which of the final result was generated by them and not by me or another AI provider. I don’t really see that happening.
The bigger issue with having AI generate complete apps goes back to the guessing I mentioned before. How can it know what your goals are for the app? There are many apps that are just slight variations from other, mostly similar apps. It cannot know which variant of anything you want unless you specifically tell it that.
