What will be next?

In my generation, I have seen missionary presentations go from overhead and slide projectors



to double slide projectors, to VHS videos




to CDs, to DVDs, to multi-media powerpoints.





What will the next step be for the generation to come?


I saw this video and wondered...


Where is the line between helpful technology vs. distracting technology?
I don't have the answers, just questions.
Tell me what you think.
