What unethical experiment do you think would be interesting to conduct?

I'd like to see if we can build hybrid computer systems using cultured animal tissue (like Cephalopod or maybe GMO human / Cephalopod), basically grown onto an array of tiny wires. Push sensory information through the tiny wires and see if the lump of cells can learn. If it does, put it in a Eva. Or a butler robot. Or a robot vaccuum.

Idk. Its an idea for a scifi novel I've had. Some company does this and what people don't realize is the supposedly autonomous systems making their lives easier are fully conscious but live tortured existences. It would get more and more lovecraftian as the cephalopod hybrids some how take over (I was thinking maybe cancer? or networked mind) and start chopping everyone to bits. Maybe they try and eat them but they have no mouth, like how an octopus arm when detach will hunt and try to feed a non-existent mouth.
