If Edison saw the future

He would see that his famous light bulb was gone. First incandescent was replaced by CFL, and then CFL was replaced by LED. The LED bulbs are over twice as efficient as CFL - compact fluorescent bulbs and contain no mercury.

Edison would see a world quite different from his. The record player replaced by a solid state MP3 player. The analog movie film replaced by digital moving pictures. Basically a new world of science.
