Most real-life personal assistants do not need to worry about their jobs being threatened by technology—at least yet. Digital assistants serve as a hands-free way to search for information but struggle to complete actions that require more complex steps, such as booking flights. Your correspondent spent several days “employing” a variety of available digital assistants. Although they can find nearby restaurants and make a booking through OpenTable, they do not yet know her well enough or have the judgment to tell her which is the “best” Italian food. Echo, Amazon’s product, can recite the definition of “personal assistant” without hesitation, but had no idea how to respond when your correspondent asked whether Echo was her personal assistant.

Why it is not necessary to worry about job replacement by technology?

(A) The digital assistants can not finish information searching for booking flights.

(B) The digital assistants are confused about the definition of the personal assistant.

(C) The digital assistants are lost in the judgment of their Personal identities.

(D) The digital assistants can not cooperate with your correspondents appropriately.
