after all, people are taking pictures to actually capture the moment
Depending on what you mean by “the moment”, I don’t think that’s really true. Modern cell phone photography doesn’t really give you what the sensors have picked up. You take a picture of your friend with his eyes closed and the phone will change the picture to have his eyes open. You take a blurry picture of the moon and your phone will enhance it to make a better picture of the moon. I mean some people hate it but a lot people do actually like it.
And they like it because they don’t really take pictures for the purpose of posterity. They don’t take a picture of their friend because they need to look back 20 years from now and remember exactly how that one plastic bag 30m in the distance was crumpled. They take the picture because they want to post to Instagram, get some likes from their friends, and maybe look back 20 years from now to remember the general vibe, and if their phone can “enhance” that for them.
If people could record a voice memo and have their phone actually make a really decent Instagram post out of it for them, I 1000% believe people would do it instead of taking an actual picture. Posting pictures is more about socializing than it is about posterity.
