So ...assuming AIs get to "choose" a body and Bubbles appears to be a MILspec super duty fighting/military chassis that (assumedly) she got when she became a solider do we further assume they get to keep whatever hardware they had from the last job they performed? You'd think the military might want that specialized hardware chassis back for re-use or just might not want it wandering around the civilian landscape. They did take back Pintsize's death ray.
Hmmmmh - Yes, they took Pintsize's laser (which, I hasten to add, he was prone to firing at anything that took his fancy, apropos nothing at all) but not his
body. Presumably, the QC-verse AIs have 'an opinion' about taking away an intelligence's body they've accustomed to - probably less extreme than humans would rate the equivalent treatment applied to one of their own, but I doubt it would qualify for 'charitably', 'enthusiastic' or 'kindly'. Their chassis' relevance to an AIs sense of identity and personhood is probably different from the equivalent relation we have with our bodies, but IMO, we've seen some indications that it's by no means 'not a big deal'.
Second, unlike Pintsize, Bubbles has given no indication of being anything but
scrupulously restrained in the application of her chassis' capabilities (admittedly, ill-positioned walls and bothersome doors seem to rank somewhat lower on her list of 'things that warrant restraint due to ethical concerns'.)
Thirdly, QC-verse is positively teeming with AIs mingling with humans while inhabiting chassis' capable of effortlessly denting steel, or
literally dis-arming each other, without any of the meatbags
present showing the slightest signs of fear or distress (*) (**)
Furthermore, we don't
know that the military hasn't already deactivated and/or removed some of her systems - what we know is that she is walking a very large and very strong chassis around ... manymany
other very large and strong AI-chassis. Could be that her most militarily relevant hardware has little to do with her chassis' structural capabilities.
And, last, but maybe not least: The only way known to us so far of incapacitating someone inhabiting the type of chassis Bubbles is wearing is a battlefield EMP specifically tailored to overcoming her military-grade chassis'
defences against EMPs. It's probably safe to assume that anything that can knock Bubbles out will likely also do seriously unpleasant things to the artificial brains of any AI in the vicinity, not to mention any critical urban infrastructure that fails to evacuate to a safe distance in a timely fashion.
So maybe, there was a staff-meeting somewhere that abruptly ended in a deafening silence after someone asked the innocuous question
"What if she says 'No'?"
(*) Note the italics - I didn't forget that humanity has a wee bit of a way to go yet before AI can consider themselves universally accepted. The casual non-reaction most Northampton residents display vis a vis 'artificial people who could dis-arm me!' walking around seems to indicate that QC-verse humanity is not at the very beginning of said learning process).
(**) No, Marten doesn't count, on account of ... of ... Being! Marten!.
