I get the idea that the understanding of AI rights is still evolving in QC-land.
Well, given that it only became illegal to treat AIs as property within the actual in-universe duration of the strip (probably no more than one or two in-universe years ago at most) then, yes, that is true. As I said yesterday, existing labour rights legislation likely was never drafted with the possibility of a sentient factory wanting the right to strike if it isn't given one day off a week and the like in mind. It's going to require the scaling of a major social and legal mountain to adjust laws and attitudes to adapt to the
fact of machine sentience.
My suggested solution? Employ two more AIs and install them in parallel with the current controlling intelligence. Then all three can work one shift whilst the other two are on down-time. We do that with human employees all the time; it just takes the right mental paradigm shift to see why that is inevitable, practical and desirable with your synthetic employees too.
