Maybe none of you would like to photo read a book more than once. But maybe someone else can make use of the recording that cuts down the time they have to spend flipping each page. If everyone made movies of every ebook they photoread and speeding them up at 15 pages a second, it would give people access to books that they can photoread at phenomenal speeds higher than the 25,000 wpm. They can easily syntopically read by just taking the books they want to read and putting them in a movie player list on your computer.
What good are mp3s? You have to encode them. Most people who listen to mp3s never encode them, they enjoy the benefits of the technology. Same goes with making movies of books everyone who views all the movies people made movies out of and sped them up so they go 15 frames per second can benefit.
We are human and we benefit by helping each other out.
