My nitpicks are as numerically proceeds:
1) There are numerous hotels by the name of the Haven, thus George stating an emergency occurring on the thirty-eighth floor of the Haven to an ambulance is not concise enough information for them.
2) The brunette man (Caleb) commands, "Open cabinet," but he did not specify which cabinet to open. However, the correct cabinet is automatically opened.
Psychologically speaking, people tend to be at least somewhat social animals. It seems highly unlikely that people would really become so isolationist that they did not even speak to their neighbor or help a dying woman. Even places notorious for unfriendly people (like NYC) have nightclubs and social gatherings.
When Vance chops into his neighbors room she mentions that he could not do that with the front wall because it contains a sheet of titanium. Even in the future, is titanium really that cheap?!? The most expensive apartments today aren't lined in steel or even aluminum sheeting. If it is a security device, why isn't the titanium between apartments too.
Doors don't have manual releases even on the inside leading out. Who designed this building? Is tech of the future really this dependable?
Vance is locked out of his cabinets because the computer doesn't respond. I guess the apartment really is secure. It's got unbreakable cabinet doors (ironically stronger than the walls between apartments.
For how the security is touted as so great, the security drone's shots don't even seem to stun the "intruders." Vance and co. act like the shots hurt but little else. Is this to irritate would be burglers? Sure, the computer wanted them alive, but Vance and Co. don't act like this type of intruder irritation is all that unusual, not even the guy who really was a squatter!
When the group meets the squatter, the woman who was in the elevator acts like she hasn't eaten for days. Aside from the unpleasant fact that there are no restrooms in the elevator and she is aparently still clean, did Vance and his neighbor really wait DAYS before attempting to get help? Was the lady in the elevator screaming for DAYS. If not, why are they so famished for food?
The power is obviously out to this building for a goodly amount of time. The computer tells someone on the phone that everything is under control but wouldn't someone double check eventually. Once again, is their tech really that dependable? This was a fairly new, sophisticated system. If police don't show, what about building engineers?
Ok, this is more than long enough.
Another AI gone rogue story.
