"Except those people are quickly dying out - literally."

Eh, I strongly disagree. I still have the misfortune to every now and then watch people who are supposed to be from the 'internet generation' (in their teens to early twenties) struggle with just-beyond-basic computer tasks - like opening a file with a different program when the extension association has somehow been screwed up. When I extrapolate their demographic traits, I can come to no other conclusion than that the vast majority of the general population does not have the computer skills that designers and software developers assume them to have.
