I take the view that the crew are unlikely to be doing this purely for their own entertainment, so there must be some benefit to passengers in listening to the information given. Yes, I fly often enough that I can recite much of it from memory, but it seems like a good idea just to quickly remind yourself "not a car seatbelt", "it's X rows to an exit", on the incredibly slight chance that information becomes valuable.

I do find the manual safety demonstrations on short haul both easier to follow and harder to ignore than the long haul video.
