Im not sure this would actually fit the definition of capitalism anymore to be honest, the term ration seems to imply that all things an employee has are just provided to them by the company instead of actually paying them and having them buy things themselves. If people arent buying anything and arent paid, then money is effectively doesnt exist for these people, and therefore isnt the basis for the power their "employer"/owner has over them. Arguably this would be closer to some sort of feudalism with central planning.
It really depends on how the rest of their society looks. Think about mining towns, with miners paid in tokens, and spent entirely at the company store.
THIS is not necessarily capitalism, it may be the FUTURE that capitalism in the PRESENT brings about. As in, so bad as to go all the way to socialism (or slavery).
This presumes ofc that humanity survives at all - b/c why would these rewards be offered to AI bots, unless the latter are modeling the behaviors of the humans that once infested the planet before the Great Purge?:-P
It is unclear to me whether that depiction of future is itself capitalism - yes it says ration, but perhaps in return for presumed work product, and/or additional food items may be available for purchase beyond that.
