I don't really feel like arguing about it right now so I will just say watch it again, and pay attention the the knowledge Kara has about it's self, the words it uses and then the reactions in the last part. There is other stuff that can actually be explained depending on the state and nature of AI in the universe so aren't necessarily plot holes so you can ignore that stuff. 

I wish they'd make a game based on the tech demo! would be awesome, I loved that demo, so emotional

Oh fine

Ok so at the start Kara demontraits that she has an encyclopedic knowladge of hundreds of languages and also knows her intended functions and also what she is (an android) so she knows that A. she was created not born and B. She is a product. Which makes the part where she acts surprised about being sold and that she thinks she was alive and just born make no sense.

Now its clear why it is written that way, because making her out to be a confused child like pretty girl is an easy way to pluck at the old heart strings. Which is understandable in a short film that you would go for the quick and easy route as you don't have time to set up more complex narative. But a plot hole is a plot hole.

There is other stuff but more nitpicky and I am to tired to bother with it right now.

Definite Blade Runner/I, Robot vibes there.

That guy who let her go will end up killing us all.

I find most times what people define as definitive plotholes are usually just things that don't seem right to that person.  Very rarely is it something undeniably wrong, perhaps that's how platholes work, I'm not very well versed in the narrative vernacular I guess.

Anyway, what you think here is a plothole I think can make sense.  There's a difference between knowing something factually and knowing its impact on you.  To me it seems plausible that you could know a bunch of facts and be able to recite the greeting you were taught/programmed with but not have it really make sense to you until you are put into the thick of it.  Like how we all know that people die if they are shot in the head but if you see it happen in front of you it's going to shock and confuse you.  

Basically you seem to have hard and fast rules for how this robot would have to act, but you can't really say how a robot that just gained consciousness would act because we've never seen that before.  We've no idea what level their conscious mind would work at just like I can't make my heart beat by thinking about it perhaps those responses are all things she can't control consciously.  

And that arguement would work if Kara wasn't you know a computer with a perfect understanding of language who can in theory proccess information faster than a normal human can. Anyway this is why I didn't want to really point it out, any plot hole can be glossed over by a mad leap in logic or in most casses for lazy writers the magic/science so advanced that it appears to be magic, card.

Someone must have changed the machine learning algorithm for this 3rd gen android. Probably the lead programmer for this android-program. Kara just social engineered the operator with her emotion. Kara will be sold and soon after runaway from her owner. You'll encounter her as a person in game. If you didn't see this tech demo you'll think she's a human. Earthlings will witch-hunt Kara but will you help her? Depends on your ideology, should their be a limit on AI? The operator is instructed to do so until this event. It became a turningpoint in which humans longer are the dominant species.

All games of quantic dream are based on emotion. Ray Kurzweil catched David Cage's imagination with his book: the singularity is near. This topic just fits Quantic Dream very well.

Too uncanny for me.

behind the scenes look

I am impressed they can generate this awe in me, still today.
