Something that really appeals to me about The Murderbot Diaries is the way names are used.
ART is ART but also Peri and Perihelion depending on who's speaking - kind of reflecting how ART is in so many places at once.
Murderbot's name is Murderbot but (at least early on) 'murderbot' is also how it refers to SecUnits generally - and then when it chooses a name to be addressed by it chooses SecUnit, and that's how its humans address it, even in private.
Names seem to be tied up with function, even to the extent that they change based on context.
And in Fugitve Telemetry so much emphasis is placed on names - from Murderbot's decision to go by SecUnit on the feed to its reaction to JollyBaby's same and the private joke about it, to the fact that it's the removal of Balin's name and identity on the feed that motivates the other bots to react.
