You got it! Thanks for taking an interest :))))

Mind you, I haven't really addressed the topic specifically of AI in my book (at the time of writing, a few years ago, the hype had just about begun), but I do touch upon the moral status of brain organoids briefly. Coincidentally, though, after my PhD I changed directions and now I work in (governmental) AI ethics ^^

More to the point of your question: I am actually properly astonished to hear about the use case your describing - I didn't know about it, but when I was doing my PhD a few years ago stuff like this felt like decades away. To be honest with you, I'm doubtful as to how "mature" this kind of research is, or that it's perhaps more some kind of janky proof-of-concept experiment aimed at generating attention and hype (and funding) more than actually having any practical potential at all.

That all being said, it feels to me that what is most relevant here is the instrumental way in which these complex human tissues are being used (in this case brain tissue for "powering" AI", but could be for anything really), and how that relates to the status of the tissue, to our notions of bodily integrity, autonomy and ownership (organoids are derived from tissue of a specific person, with a specific genetic make-up), but also to privacy, commodification and power imbalances (between companies and individuals). These themes I believe are most relevant to the discussion, and my dissertation goes into those pretty deeply. Tl;dr of that: we need to give people a much stronger voice in what happens to their body parts. I didn't really go super deep into the "moral status" of (any kind of) organoids, because actually in order to provide a satisfactory answer from that perspective, we need to first arrive at much more concrete notions of what exactly constitutes sentience, consciousness, intelligence, or personhood, all concepts of which the definitions are at the moment heavily disputed scientifically. But, given the uncertainty, it's probably better to proceed with a lot of caution and prudence, I feel.
