You have to design UI for 'digital natives' to be just as user friendly as you would for baby boomers that didn't see their first computer until after they were grown. Both of them would be equally lost if you plopped them down at a terminal with nothing but a blinking cursor. This is generalizing, of course, there are exceptions.
Anecdotally the only thing that separates a 9 year old and a 60 year old is that the 60 year old won't want to touch a computer because they are afraid they will break something and the 9 year old will mash away until they get where they want to go. Neither knows or cares how or why it works.
