I always forget and Google always does a spectacular job of doing a April 1 joke...I am busy reading about the new Autopilot feature in Gmail on this page and going "WOW" this is amazing and I finally realize that it is April Fools when I read this: What happens if a sender and recipient both have Autopilot on? Two Gmail accounts can happily converse with each other for up to three messages each. Beyond that, our experiments have shown a significant decline in the quality ranking of Autopilot's responses and further messages may commit you to dinner parties or baby namings in which you have no interest.
