Youngsters these days.

Sigh... How many times have I heard "okay boomer" from my 24 year old son? Too many to count. However, after a lifetime of good sound in my house he knows what's sounds good and what's mediocre. I'm almost 64 (I was almost 40 when he was born). He's always known how important good sound quality is; proven by his wanting to use my home theater for his entertaining with his friends to watch their movies. His generation, as stated above, is not attached to the media we love so much. My CDs and LPs are my treasures and I love playing them on very decent system. When he moved out recently He took his pair of (British made) B&W DM601s to connect to his big TV via a Yamaha receiver. (I gave him both.) True to his generation, however, he told me to keep the Pro-Ject turntable (another gift) because he had no room and only five LPs. He's content on streaming his music. Different strokes, I guess...

I personally believe “Ok Boomer,” is just another divide and conquer tactic. Right vs Left. Red vs. Blue. Boomer vs Millenial/Gen Z. My Team vs Your Team.

Google trends shows that “Ok boomer” virtually didn’t exist before October 2019 after it was popularized on TikTok and right around when a whole bunch of news articles came out.

A quick google search for news articles turns up:

New York Times: “Ok boomer marks the end of friendly generational relationships.”

Washington Post: “Ok boomer, the kids are fighting back.”

NBC: “Ok boomer is dividing generations.”

Is it really NBC? Or is the fact that you are reporting on it and reaching millions of viewers and bringing the term into mainstream and generating division what’s really going on? If you hadn’t reported on it, would it have remained an obscure TikTok reference because who the hell even knows what TikTok is?

The solution? Don’t use the term. The last thing we need is more things dividing us. We are way more similar than we are different (whatever team you’re on).

Being north of 60 has caused me to temper my thoughts with the younger generation many times. In certain instances, it is as difficult as describing what color is to a person that was born without vision. In this case, I enjoy reading the liner notes and looking at album/CD artwork as much as listening to the music. Kind of like looking at the back of a cereal box at breakfast. It’s just part of the enjoyment. 

I resisted streaming for a long time. I think the technical issues have now been resolved to the point streaming should be indistinguishable from other physical digital media, or maybe better. I had a few CDs that skipped, but they ripped just fine.
I get the idea of enjoying the collection you have, but I hope I never when get to the point of no longer being interested in discovering something new. I also didn’t manage to buy every album I ever wanted to listen to. With streaming I can go back and hear albums I barely remember or completely missed. I’m so glad I’m no longer stagnant. I listen to my system more than I had in years.
Sometimes “Ok, boomer” is the appropriate dismissive phrase for an old dog that has no interest in learning a new trick, unable to see the obvious benefit because they think they already know it all. Your grandson was trying to help you.
“Youth cannot know how age thinks and feels. But old men are guilty if they forget what it was to be young.”

My two boys are 23 and 18. The older one is in grad school and listens to an amazing array of music. I guess I started the fire and he has fanned the flames on his own. We turn each other on to new to us music on a regular basis. He had my old Kenwood amp and AR14 speakers in undergrad but the ARs were too big to fit in the Prius on the way out west so I bought him a pair of Quads when he got there - he is still rocking the Kenwood. That means his younger brother is getting the ARs for high school graduation along with a new Yamaha amp. He has recently found Pink Floyd and his tastes are really developing quickly - he’ll be teaching me new tricks soon. 
My point is that I see folks on here belittling their generation and it really pisses me off. Sure there are plenty of youngsters out there that don’t have much substance to them but that was true in my day too - look at all the folks that ruined my high school experience with disco. The fact is these kids will lead us out of our current mess. 
Regarding streaming - I am a huge fan. I have a gazillion CDs and hundreds of records. I still enjoy vinyl very much. But the amount of new music I’ve been introduced and reintroduced to through streaming is incredible. Bob Dylan has jumped out of my Mytek Manhatten and is currently standing in my room. 
From my vantage point The Kids are Alright. YMMV.
