Word meaning society ruled by Artificial General Intelligence?

The word I was trying to recall is algocracy. I realize this isn't so much rule by AGI, but moreso society where law is executed as code, which could include an AI program, but might also include blockchain smart-contract-based legal systems.

I know this must be the word because I was ran into this term in a transhumanist forum originally, so this adds up.

I do like people's answer automatocracy though; that seems like a much better word to describe rule by AGI specifically.

According to Wikipedia, "automata" (the plural of automaton) is a theoretical branch of computer science that has played a major role in artificial intelligence. The word you are looking for, therefore, would be "Automatocracy". See Wikipedia link

Though the following word doesn't begin with the letter 'a', Wiktionary lists

robotocracy (uncountable)

rule by robots

The robots involved would obviously have to possess intelligence at some level; [Wikipedia] licenses this (though the very existence of the word virtually demands it) here:

Robots can be autonomous

And in this article:

Autonomous robotics is usually considered to be a subfield of artificial intelligence, robotics, and information engineering

though of course outward appearance need not be humanoid.

The term automatocracy is mentioned (with the equivalent of scare quotes) in this Wikipedia article on 'Political ideas in Science Fiction', but has a very limited circulation. Though it has been used outside the SF community; this Reddit article on politics uses the term. It is perhaps borderline acceptable, needing scare quotes outside SF at the moment.
