Emily: Do you like technology devices such as smartphones and computers, Brian?
Brian: Yes, I do. I read news about them all the time.
Emily: What do you think a future smartphone will look like?
Brian: Well, it's not easy to predict because technology develops every second of every day, but I think smartphones will be much thinner and easy to be folded.
Emily: Will it be as thin as a piece of paper?
Brian: Possibly! The phone might have a plastic screen and its appearance will look like a sheet of A5 paper, or it won't even have a physical screen at all.
Emily: What do you mean by having no screen?
Brian: By using holograms, of course. A 3D image of the screen will pop up whenever you need to use it.
Emily: How can we view the information and interact with others?
Brian: Wow! But it sounds like science-fiction films.
Emily: It would be great if they still have it.
Brian: I know. Actually, people are using holograms in some live concerts and conferences nowadays.
Emily: But smartphone's screen should be more interactive and nicer. I prefer a smartphone which is fashionable and real.
Brian: Well, these are just my predictions. The future smartphone might still keep its physical screen.
Emily: So what do you think a future smartphone will look like?
