Sophia Robot and Erica Android

I have been commently mainly in the past about Sophia (Hanson Robotics) but unfortunately have been neglecting the work of Hiroshi Ishiguro (mainly because I cannot speak Japanese). Here is an opportunity to see both AI in a single video.

The commentator at the end questions Erica's ability to express emotions. Humans themselves do not consistently express emotions nor do some do it very well. I am uncertain if it is necessary for items with designed intelligence to experience emotions as humans do. A dog is capable of expressing emotions - happiness and sadness - but there is not they don't seem to express some emotions that humans are capable of- hubris or schadenfreude. It is possible that designed intelligences might be capable of emotions that we are incapable of conceiving.

Neither Sophia nor Erica have advanced to this level but I am encouraged that Erica can speak Canadian eh...
