Barrier to entry for commercial or useful GPTs/Plugins/"Agents" is almost non-existant since its just a str.concat(hiddenprompt, user_prompt), the secret sauce (ie the weights, chat timeout and context length) are already generated/limited by OpenAI and they already have the content moderation/"hr dept" baked in at the weights level. So even if one was to create a "story writer helper" GPT, i don't see how it would be of any value generating new, unique and interesting content other than the prompt recipes we already have on reddit/r/chatgpt (heres 1000 prompts for every use case) that creates netflix like plots (inclusively diverse casting across ethnicities and orientations, socially conscious storylines, modern jargon-filled dialogue, themes of empowerment, progressive characters, and non-traditional relationship dynamics).

This will most likely be like the google play store with a 99% of GPTs being a repackaged public prompt.
