As I understand it (thanks to my big-brained friend sam notedchampagne ily sam) one of the main things this show is trying to communicate is the real cost that everything we see done has. Work, time, effort, coordination - when the hive is getting Carol her 'pirate lady', we see her walk to the platform, we are made to consider the expertise it takes to make a plane work by seeing every turbine turn on; we see the plane take off, we see her arrive at the airport, we see her take a shower, we see the multiple people preparing her outfit and hair, we see her get dressed. When Carol asks for her supermarket back, we see the trucks, we see the dozen or so people putting it back together, we see the clock tick up an hour or so.
Pluribus is slow specifically because it wants to make you sit with that, and thus understand what it means you see the characters engaging with the hive and asking it for things.
To Carol, the other humans, and the viewer, it may seem like the hive are miracle-workers. But they're not. Every single thing they do requires tangible effort and resources. And all of it has a cost.
