I've met (teaching) too many teens that can't really use a computer. The procedural and hierarchical structure abstractions, even the desktop metaphor is lost on them. Idk if there's much of a future for widespread general purpose computing. The situation is understandable, as it's way more difficult to get the gist of how your system works nowadays than 20-30 years ago, and they're really using mobile paradigms that don't expect you to think about it, but I don't think it's a good prospect.
