are unaware of. pete: great point. i actually learned can you turn off the facial recognition aspect inside your profile. facebook says nothing to see here. we have reached out to them and this was their statement back to us. they said the 10-year challenge is a user generated people that started on its own without our involvement. it's evidence of the fun people have on facebook and that's it you are right there. is a big trust gap here. >> look, they also said look, there is all sorts of pictures on facebook. however, though, for artificial intelligence to work properly it needs what's called machine learning. to do that you need to put these things in context. i have now told the machine learning this is a picture of me 10 years ago. here is a picture of me today. here is the context. walls it at night? was i wearing sunglasses? was i wearing a hat? all the machine learning needs to train so the artificial intelligence gets really better about picking you out in a crowd of people, ellwood when you have a hat on.
