I have begun to watch all movies with subtitles turned on. This is because a) I already watch a lot of subtitled foreign-language films but mostly b) as my brain deteriorates, it helps me follow the movie better. It's really helpful in a movie like Lord of the Rings, with all its odd proper nouns. Sauron? Saruman? What?
Soon, I will require my smartphone to provide subtitles to everyday encounters, like at the hardware store or on the phone with customer service. I'm sorry, your name is Saruman? Solomon? What?
(Live subtitles might not be so far off, as i wrote a lot of this post using the voice-recognition software built into Android. Other than fixing a few wrong words, and adding punctuation and capital letters, these are mostly words I didn't type.)
