Really nice article with lots of nifty technical stuff about optics, lasers, etc. But this thread also has a lot of thoughtful comments that question the actual bottom line financial potential of this nifty technical stuff. Here's much of the rest between the nifty technology and the financial bottom line: The art, entertainment, content, etc. E.g., I've never paid much attention to ballet. Since early on I liked music and classical music, I have some CDs of the music to a few of the famous ballets, right, The Nutcracker, Swan Lake, Coppélia. But, right, via YouTube, it was easy, e.g., to watch some of Coppélia, so I did. It's fun! It's a light comedy, with a cute story by Hoffmann (right, as in Tales of Hoffmann), and a LOT of really pretty girls (right, I'm a human male!) acting really cute! Movies and the OP? I'm coming back to that with Coppélia as an example! The YouTube performance I watched was from The Australian Ballet. Well, too soon that performance was taken down on YouTube. Bummer! But, if The Australian Ballet had used YouTube just as a free sample, then it worked because I bought the DVD. Now the DVD of Coppélia on my computer is really nice, nicer to watch than via YouTube. No matter how the work goes on a day, a little Coppélia will make the day a lot better. Why? Lasers? Nope! Instead of lasers, what's good is just the art, entertainment, content, and these come across quite nicely via the DVD. The music is terrific; the story is cute; the girls are really pretty. Drive 50 miles to a 3D, 4K laser movie version at big bucks? Likely not. Why? There's an old point: Once long ago a guy asked a child which he liked better, radio dramas or TV dramas. The boy said radio. For why, he said, "The pictures are much better on radio.". Yup. Sorry laser guys: Some of the best pictures are what the viewer forms in their head from just hints from the content itself. Sit down, laser guys: I have a DVD of the original 1933 King Kong. It's just black and white, but it's still fun! The nicest part is the interplay with the Fay Wary character, the poor, pretty, sweet, naive girl, the older, powerful, assertive, rich movie producer, the hard boiled crew of the ship, etc., the beauty and beast theme -- all that comes across very nicely with just that old 1933 black and white version. My wife understood drama: So, once she took us to a summer stock play, only a few actors, a small stage, a small audience, and afterward pointed out to me how there is some magic to the theater, that the audience can really get into the story and experience with just the hints of such meager production values. Not nearly new since such drama goes way back in English literature and the ancient Greek theater. Net, the main issue is the content, not the technology.
