I haven't seen it, but the premise is that you have a second self who is trapped at work and wants to escape. That's really not the same thing, and misses the point of my drug scenario, which is that pain and (simple) suffering outside of meaning don't have moral weight. In this TV show the inside-work-selves are leading meaningfully miserable lives, with the frustrated cognitive desire to escape. They have knowledge-forming thought processes that are being wasted.
I mean, OK, there's plenty of further tricky sci-fi dilemmas along these lines. But I was interested in pain in the context of animal rights, obviously, this being a thread about whales.
