What a coincidence. I was just about to create a poll of this exact same thing.
So taking the opportunity to ask my own question: I know 3rd is more commonly used, but is it true that 1st pov is becoming more and more popular between readers nowadays?
If it has 'personality' then I would say yes.
Edit: It doesn't even need to be an AI personality. It could be just a humanizing trait you give yo it. Like its pilot talking to it (even though the Mecha is just a machine) and giving him personality of its own. Idk how to explain it lol
But with all honestly, if it were to become the most famous sentence in all of existence, then I think this is the correct option:
"The freedom of one ends where the freedom of another begins."
You all will never find me! I'm fighting the corruption of representatives from the shadows (of my mother's basement).
Though, if you do find me, at least make sure the sock is clean please..
