However, you're not answering your comment's grandparent: how to avoid, cope with, or assume away the concern that a super-high-tech economy will leave unemployed people who aren't intellectually sophisticated enough to participate.
Threats to survival do tend to motivate "almost everybody" to attempt new skills, or attempt to change things in their favor. I deliberately avoided saying what the changes ought to be. And I don't think there are real, present threats to survival for most of us. I don't think it's a good idea to rain down mandates on "everybody else," when society is already discovering better means by working organically. I like to think of that as innovation.
My main intent in posting was to point out that there are solutions being found -- not by the "invisible hand" of economics, but by the collaborative efforts of the non-intellectual non-sophisticated "unwilling participants." Though I think education eventually has the highest payoff, I enjoy working at a community level with the innovation happening all around me.
Is changing your intellectual sophistication hard? I mean, I learn programming by basically bashing my fingers against the keyboard. The concepts aren't difficult to learn, but it require tons of practice to become competent.
(I should have said "explain away" instead of "assume away.")
Uhm, how isolated are you from large swaths of society, to ask this question? The answer is yes, once a person matures into adulthood if they haven't acquired this and an appreciation for learning they almost certainly aren't going to. There are people who regard most intellectual activity with disinterest in the best case, and outright hostility in the worst. This group of people is known as "almost everybody in the world".
As for what to do with them, probably the most consistent approach if you want to stick to something resembling market economics is to let them starve. My objection to that isn't so much moral as it is practical (i.e. I dislike riots), and I favor giving them money instead.
