Okay. I use your same question on all 3 AIs I have. Of course the worst answerer is - Alexa!! With her 'I don't knows'. Ugh.
Google and Cortana just pull up current affairs word. But... I did ask all of them what they think of current president. LOL Cortana wins!! She has the most comedic response. If you have Cortana try it. Oh wow further searching of Cortana's answer, it actually is true. There you go, Cortana wins with the most accurate(?) answer, I guess, for an AI.
Cortana actually answered me in a full sentence, too. No search pull up like Google did.
Yap Cortana is the only one answering me coherently with my Hillary and Obama question, too.
