That’s very true, the speed that they absorb information is astounding, but of course they also filter out a lot they don’t find immediately useful. They’re impressed with claims, because they don’t have the experience, and haven’t learned to fact check. Though I wouldn’t describe them as gullible in the sense an adult can be.
I remember my dim-witted ex complaining that our granddaughter had done something to her mobile. No smart phones then, or touch screens.
I said have you tried holding down the two top most buttons at the edge of the phone? I did it and it was sorted. She thought I had some supernatural ability, until I pointed out that our granddaughter had very small hands, and would press and hold only what she could reach with her thumbs.
By the time smart phones were well established all the grandchildren had started to accelerate away from us in understanding them.
I’ll never forget my grandson dragging his hand across my laptop screen, and telling me it wasn’t working. To him all screens were touch screens.
