It's the internet... people always only talk about the extremes. Look at concerts for example, you have two extremes:
1) don't take photos/videos at all, enjoy the concert!
2) hold your phone above your head for the whole concert and record and instagram everything, every song, every word said between songs, everything.
Both options suck, and most discussons just use the extremes like those above.
There is always a middle ground, where you take a few photos, maybe a short video, and as you said, in a few years, you'll be scrolling down your gallery and suddenly remember that (looking at metadata) on june 7th 2019 you were at a concert of ThatRandomBand, and it'll be a nice memory to keep and remember. Noone will watch an hour of video with distorted audio, and you'll forget a bunch of stuff not saved anywhere, but a photo here and there is always a nice thing to have.
