I've posted this here on namePros a few of days back: Are domain names becoming less valuable in the near future?
So you can see that I'm aware of this current trend with Ai.
However, I don't think that GPT technology has what it takes to be a decent domain investor.
The main reason is, as the GPT definition suggests, these are Generative Pre-trained Transformers. What that means is, it's a system that was trained with existing content to generate similar sounding content.
So at best, a good GPT will sound like an average domainer, who takes in some good advices from great domainers, but at the same time, also takes in some poor understanding from beginning domainers.
Besides, at the very core of a decent domainer, there must exist the understanding and intuition of new and emerging trends. GPT tech. by definition has neither. It can only generate content based on existing content, it can't predict the future. There are other types of data analysis Ai that can possibly make some predictions, however, I'm not aware of any such innovation that can predict domain name trends.
So unless something significantly changes in the Ai tech to incorporate business naming prediction for the future, we'll not see someone becoming a decent domainer only by taking suggestions from GPT. Also, even if Ai catches up with newer innovations, it'll most certainly not be called GPT - because it'll not be Generative Pre-trained Transformer
