I'm watching a documentary regarding the history/origin of blockchain.
Which documentary? A link would help.
probably the OP means this video
https://www.youtube.com/watch?v=gK2jkkB2yycIt is a nice idea for a new terminator movie, and an interesting concept in general, no doubt. Definitely it is thinking outside the box.
The concept is about AI constructing Bitcoin and Blockchain in order to create the incentive for people to dedicate the enormous computing power for mining. Then, the AI would be able to live a fairly convenient living inside all that computing power.
EDIT: it is a different video than the link from the post above, much shorter, so I will leave it here. It is 8 mins.
