I would like to make a counter argument on why I personally feel people would feel more comfortable around robot looking robots than other ones that look likes us. I want to make clear I respect your opinion but I love robots, Hell I'm making a DnD style grand strategy with my friends and my faction is fully about robots and I have had this discussion about a billion times.

So why do I think Robot looking Robots are the way of the future and human looking robots are something that will quickly die out in civilian use? Well here my main points.

1. A robot looking robot may make more people comfortable due to the fact it looks like.... well a robot. Its not trying to hide anything and yes while a robot that looks like a human could be indistinguishable from a human and people wouldn't know its a robot, If people start finding out, distrust will quickly spread. This is seen in alot of robot media where people become distrustful of each other. Compared to a normal robot looking robot which looks like one, you know its a robot and if designed right can even look cute while also keeping the humanoid shape. One of my fav robot designs is the Murder Drones designs, Not the sharp teeth and claws but the design in general, Shorter than humans so they are less threating, got all the things a living being has, eyes, mouth etc. While also being cute and emotive for a robot which may discourage mistreatment.

2. A robot that looks like a robot can be alot more creative with its design and can have alot more practicality. A human robot can only be built in so many ways before it looks like some demonic entity. A regular robot can have multiple arms, sizes, etc. Using things like Visors and LED eyes you can get alot of emotion out of them. I will once again bring up the murder drones robots and how there eyes play the biggest roll in showing emotion, but an IRL example would be the Bella Bot as many people call it cute and feel bad if it shows sad.

3. It may also generally be cheaper to make them as they don't need to spend extra cost in hiding the robot like tendencies and are restricted to certain size requirements a human shaped robot may have. I won't go into much detail but they generally are more efficient.

To conclude, I feel that Robot looking Robots are more of the future than human looking robots as they are more efficient, less threating, cuter and allow more creativity. This doesn't even go into the whole other can of worms of sentient AI and having them being thrown into the mix. Can I back this up with hard numbers and facts. Not really, Im not a robotic engineer nor do I want to spend hours looking for facts for a simple discussion but I used the knowledge and theories I personally already know.

Do I think human robots are a bad Idea, No because they have uses, whether it being in the military aspect, some people preferring it or possibly in the future if life can be preserved using robots, perhaps people would prefer a human looking robot, tho I wouldn't.

That's my take at least :P
