According to a different article I read, a laser is used to engrave it. An optical microscope is used to read it. It's digital information. So the reading part is going to have to develop.

It's obviously only a proof of concept at this time. The only threat to film that I can see is storage of movies on film, so it would be one more thing film is no longer used for.
