I wasn’t aware of this:
Cortana is a fictional synthetic intelligence character in the Halo video game series. Voiced by Jen Taylor, she appears in and its sequels, Halo 2, Halo 3, Halo 4 and Halo 5: Guardians
Maybe because I don’t play shoot em up games.
Made Microsoft a Mint.
So naming their answer to Siri "Cortana" didn't come as a surprise to me.
Now they have went and made her a Villain.
Good going there guys :/
