Sometimes is just impossible (physical laws or limitations of the current technology). I can't have 40 ms ping time with a game server on the other side of the world no matter what and my 4G connection slows down when it snows. Ok, I should pay somebody a relatively huge sum to lay a fiber optic cable to my home :-) An AI to fill in the blank of a video call (degenerate case: a still picture) is OK for me. Sending me a summary instead of a book, a trailer instead of a movie does not. By the way, AIs were filling in the blank of video calls when bandwidth got low in a Fire upon the Deep. The calls were between far away spaceships, probably very superluminal transmissions because of how physics work in that book.
