I guess that if the robot is programmed for sex, he is consenting to it by default.
And I guess that the fact they can adjust to our preferences is just to stick with people's fantasy (like your ideal guy is like X so you want a robot like X, they are a sex doll after all)
Consent can only be given consciously, so if the robot isn't self aware, consent doesn't apply. Consent isn't words, it's emotion, you can say you consent and still not want what's happening. Honestly, everything you asked is entirely dependent on whether or not the robot is sentient, if it's inanimate then turning it off wouldn't be "killing it" or "putting it in a coma" as it isn't alive.
then I would wonder how we can know whether a robot is sentient or not if it is designed to imitate sentience in so many aspects? It clearly imitates human sentient actions, so we probably couldn't judge whether the robot is sentient based on his behaviour, but we also can't know whether the robot is minded because we're ourselves and not him, so we cannot have full confidence in saying he is or is not sentient, can we?
No, i don't think so. If it can have it's own thoughts, it's sentient, if it's every action and thought is based on predetermined code then it isn't sentient. Sentience is basically just being self aware.
so unless we know the entire scope of what is predetermined by the coding we cannot know if it has self-awareness. on the other hand, some people (mostly religious people) argue that our universe and our own thoughts and actions are also predetermined **ponders the reality of life** - well, I never agreed with determinists but I do wonder if humans might accidentally programme something that then ends up being sentient by accident almost, because we don't know what exactly makes us conscious - we can't really determine what makes us conscious since it's not really something we can explain through neuroscientific brainimaging or whatever other scientific method
I'm not sure the concept of destiny is the same as programming? Destiny is basically the predetermined choices we ourselves will make, with full sentience. We choose the acts ourselves. Free will is a thing in that very same religion. Robots don't actively make choices.
But if we're created to make a certain predetermined choice, isn't that the same as when a robot engineer creates a robot and programmes it to make a certain predetermined choice?
No, because the robot isn't choosing the actions itself. Lets say it's destiny is to grab a fork, if it's sentient then it'll choose to grab it. It'll acknowledge the action. Programming isn't the same, it's just an order.
I totally love it but I also have philosophical questions about this.
Does it count as consent if the robot is programmed to do it? Does the concept of consent apply?
If the owner falls in love with the robot and the robot reciprocates, is that part of the programming or is the robot able to be more than what he's programmed to be?
Is shutting him off equal to killing him or at least putting him in a temporary coma in human terms?
Does people's desire to have something like that mean we as humans have an urge to possess someone and adjust them to our preferences rather than to fall for someone with all of their mistakes, aspects you don't like, preferences you don't share and differences you have to overcome together? Is it unhealthy to have the urge to completely own someone and replace human connection with idealised versions of our desires? And what does this power over a robot mean? Is it the same as the power over an object that doesn't imitate a human, like how you can treat your phone however you like, or do we have responsibility to treat the robot well?
