No, they really were (hilariously) dumb and simple. Of the top of my head I remember their capital was named “Big Strong City”, their “Red Alert” was “Red Alarm” (it’s funny in context) and they didn’t really understand that’s an emergency, and despite being corrected multiple times by the woman herself, they kept thinking captain Carol Freeman was captain Kathryn Janeway. For reference, one of them in black and the other is white.
No. And this reminds me of the “meat proxies” we see now who are “smart” and “powerful” using Claude.
