I have a degree in IT, specialising in AI, NI and cybernetics, but would never use it to write my ads, simply because I am a human writing TO humans and have a personal desire to ensure 100% accuracy and relevance.

A computer generated advert will never say what I personally wish to convey, but remember that AI needs to 'learn' so the more it is used, the better it becomes  and if some sellers are happy to rely upon it, then good luck to them
