Looks like Apple’s Siri is jealous of Microsoft’s Cortana.
Here is how the conversation went between a user and Siri on an iPhone.
User: Cortana, get me today’s movie times.
Siri: Who’s Cortana?
User: Oops I meant Siri
Siri: Who is Cortana?
User: Please get me the movie times.
Siri: Maybe you should ask Cortana for the movie times.
This is just for fun. Siri doesn’t actually respond to user’s queries as given above.
