I sort of doubt there's really a so-called generational gap. I suspect it's just the usual click bait.

I'm sorry I don't have the link but there actually was an online lament by professional sound crews for film/TV that I read a few months back. Sound is apparently compromised by the usual suspects: creative egos, competing priorities, actors' failure to enunciate clearly, and failure to appreciate the technical nature of audio recording. In some cases, the director instructs the sound crew to "capture" the performance after the scene is shot. I've never worked on a set before so I'll leave it at that and say that as an older person, I love CC and use it all the time whether I'm other-tasking or not!
