Yeah... no. I'm going to pass. The premise is bad from any angle. In the case of businesses, why "create" another "Amazon" and compete with other brands when the focus should be on getting customers through my sales funnel? For developers is much worse since they are going to copy Amazon's model with brands that found a niche: Amazon Basics. In this case, it'll be OpenAI "core" (or something like that), where you do all the work, and when your "app" is somewhat famous enough or getting traction, they'll copy it, rebrand it, and bombard all old and new customers to use it instead of yours.
I'mma call it now just for the fun of it: This will go the way of their "GPT" store.
Companies like OpenTable that make money on the backend for connecting you with the restaurant will happily partner with OpenAI on this.
There are plenty of brokers that will add immense value to ChatGPT for free and if users go there looking for something, it's only a matter of time.
Right now, I only like using the chat interface to answer questions I can't quite form into searches, but I also don't go directly to a chat bot to book dinner reservations. However, if I'm using the service to riff on ideas for a romantic thing to do with my partner, and it somehow leads me to resturant reservations, I do think I would engage with it and come back to ChatGPT in the future for novel interactions like that.
