Despite our own familiarity with technology, we watch baffled as our own children use it in ways that seem absurd to us - they seem to film or photograph everything they do and spend all their time on YouTube and Instagram.
It's almost like living in a fantasy world - you portray your best self online and gain approbation through likes and views.
This fixation on image is no doubt damaging in some ways, but in others, it's a new variation on what has always existed.
In the 1700s there was no Photoshop, but the portraits from the time all look strikingly similar - the artists painted their subjects as close to the beauty ideal as possible, making the waist a little narrower, the skin a little smoother, the eyes a little rounder.
No matter the technology of the day, human behaviour doesn't really change, but adapts to the times.
Our children may spend more time on their devices than ever before.
But that doesn't change our priorities as parents, grandparents, aunties and uncles to make sure these children grow into adults with good hearts and strong minds, whether they learn that through educational computer games or by running wild in fields of daisies.
