It's basically a derogatory term for AI. I've seen it used the same way a slur would be used to berate a person.
Got that from context; I’m just baffled, really. Seeing people call AI “clankers” is like watching a third grader call another “poopy head”. It’s just depressingly infantile.
It's a reference from Star Wars if you really don't know. People say things they hear, I don't know what else to tell you.
