A couple of years ago after watching Gravity, two girls in front of me were really impressed with and had the following short conversation:

G1: "That was such a cool movie!"

G2: "I was really impressed by the special effects in 3D"

G1: "I know, right? I can't wait to live in the future, don't you think we'll have technology to see 3D everyday everywhere"

G2: "I don't even think you'll need the glasses"
