Out of touch

We bought a replacement car, which came with a trial of Sirius. I am getting fliers and emails urging me to sign up for the low (or "current") price and suggesting channels to entice me. What does? Talk radio--hardly. Sports--no. "Every music genre" that didn't list the only channel I'd be interested in. "Nonstop news" sounds like Babel torture. "So much comedy"--not a diet of it, thank you, and most of the modern comedian shorts youtube offers up are more bitter than funny.

My wife was on the phone with someone talking about a child interested in manga. I looked it up. I'd heard of Isekai--I'd written something that might be classed as "portal fiction" (though not Isekai)--but most of the classifications were new to me. I'd have to spend quite a while at the library reading through stuff to get up to speed, and even then I don't know if the library carries some of the more "adult" stuff. It might--libraries have been getting a little odd lately.

Maybe a movie a year at the theaters, no broadcast TV, no cable TV... The HBO/Netflix/etc produced content I haven't seen at all. Young adult conversations are replete with references to catch phrases from shows I've barely heard of. I'm told the caliber of the work is better than the old 60's/70's TV shows (which I'm not interested in rewatching). OK.

The book of Daniel says the Babylonians trained their most promising captives in the language and literature of the Babylonians--presumably because the way the language is used references the literature for additional meanings. How far out of touch can I be before communication becomes difficult?

Some words have already changed meanings.
