I doubt it that AI is already that far evolved that it would be capable of setting up such a big and beautiful thing.
I do think AI well be the next step after RPA (Robotic Process Automation).
To be honest, AI scares me a little bit. But as long as we can pull the plug, we will be alright!
So no, I don't believe that AI created the bitcoin but I can't rule it out!

All three of your reasons as to why blockchains have a native currency fit into this idea perfectly. What do you think?

After rereading the reason, it could make sense. The AI would have determined that people will do almost everything to make a profit and setup the cryptocurrency as bait.
