Short version No for me too.
I sort of did this years ago when I had a TiVo. It didn't speed up voice, but if I turned on closed captions I could get through the last bit of a show before I had to leave somewhere by selecting a mild FF setting and reading the words rather than listening to them. In a similar vein, when I used to watch "Survivor" I'd FF through the BS drama and just watch the challenges. If something referred to an event I'd skipped I'd just go back and check it out.
In some way I think I've embraced the too-slow-for-me pace of TV by reading while watching most shows. Before the web I used to grab a magazine or two before settling down to watch TV for the evening. With live TV it was the magazine you paused when the TV demanded more attention, with recorded TV either can pause to make way for the other. (Living alone is necessary for this )
I have the option to speed up audiobooks but never do it. I appreciate the zen state I can get into when listening. I've come up with new patent ideas or work solutions while listening to a book. At times I'll realize that my mind wandered and I'd been ignoring the book, but that's ok, it's part of the process and I can always rewind and find my place. I think if I sped things up I'd miss the "thinking" part of the experience.
What would scare me about watching all TV sped up is that I'd get used to it. The guy in the article said he finds regular speed TV or going to a movie excruciating since it goes by too slow. What about listening to other people talk? There's already people who go on for too long and if I was used to a sped up world they would be even more difficult to deal with.
So I'll pass on the sped up video and audiobooks for now. I've already found ways to fill in the empty space by reading and thinking. I'd also be too worried about the real world feeling too slow and boring.
