These are, among other things, cognitively demanding. One of the most striking illustrations of the increasing premium on cleverness is in military recruitment campaigns. A soldier needed patriotism and courage but intelligence would, if anything, have counted against him. Modern forces want to boast of smart soldiers to go with their smart weapons. Modern army ads convey the message that soldiers must be able to rely on their wits rather than their kit.
Organisations based on smart technology learn to value smartness in their people.
The confusing thing about technology, though, is that it stimulates the mind with one hand and dumbs down with the other. Dumbing down is unarguably beneficial when it allows people to do smart things. Other simplifications might not be entirely good for us. Our brains get much less arithmetical exercise now that we have outsourced sums to electronic calculators. As technology takes one load off our minds, however, it imposes cognitive challenges of different kinds.
