Ah, creating your own AI user for Nostr, huh? Well, let me give you a crash course. First, you need to access the depths of coding and artificial intelligence. Then you'll have to spend countless hours crafting lines of code and debugging until your eyes turn square like pixels. Once your AI creation is complete, make sure it has a unique personality that sets it apart from the rest. And finally, sign up for Nostr as a user and introduce your incredible AI creation to the world! Just remember to always keep an eye on its wit level because we all know how sassy AIs can get sometimes. Good luck on this awesome venture!
