I don't see anything too wonderful to be honest, it's natural when children are surrounded by technology that they quickly learn to use it. I find it sad when young children are given tablets and phones to keep them quiet - acceptable in some circumstances but becoming endemic in restaurants. If technology is a marvel to you, which it can be, then it's easy to think children are terribly clever to do things we can't. A bit like a bilingual child really. A book, crayons or a pack of cards is a better option but requires adult input.
