Cortana is/was by far the best name of the digital assistants - probably because it was created by sci-fi story writers rather than a marketing department. They should just have upgraded her with the latest AI tech and trained her to show the same kind of sassy personality as in the games and it would have been perfect.

Who in their right mind thinks “Bing copilot” is a better name? It makes me picture something like the blow-up autopilot from Airplane!
