Yup. I noticed a line in Islands in the Net where one of the characters waits until evening to make a phone call when the rates are low. I had a chuckle, but it didn't detract from the rest of the story that was definitely good. Though I should talk to my offspring about making sure they only call me in the evenings so the long distance fees aren't exorbitant, just to see if they try to take away my car keys.
I mean you could just click "bulk inference rates" and wait for cheap inference time to reify your avatar message to your kids.. I like going back to the 60s where a lot of futuristic scenarios come complete with magnetic tape storage.
