I wonder if in 30 years people will be showing off their photo albums to which their kids will wonder why aside from the images not being 3d. That the photos have had detail purposely brushed out by means of superficial Instagram filters.

That's not what instagram does. Instagram replaces noise and poor color with an artsy layer. The missing detail was never there (or if it was, t was ugly detail like harsh shadows and pimples)

Shots with good cameras and lighting and faces don't get instagrammed.

You're right. I did find it interesting to contemplate though, and has encouraged me to reconsider my requirements next time I travel, or just in life.
