I believe you're just reading the surface message here. When I read the article, what I felt was "man, he's really railing against a general decline in
curiosity". To paraphrase Marvin of HHGttG fame, our computers may lament so -- here I am, a GENERAL PURPOSE COMPUTER in your pocket, and all you ask me to do is to tell your friends what you had for lunch?
Sadly, I've been part of this decline in curiosity as well. My son, when he was 4 years old, reminded me of that unadulterated fascination. (translated)
son: "Look, dad!"
me: (looking up) "What?"
son: "Tree!"
... and I humbly thanked him for the lesson of missing a magnificent glorious tree right there in front of my eyes. Its a tree! It made itself mostly from the contents of air by trapping energy from the sun! How cool is that!
All that said, the above anecdote is promising too. If only, we'd nurture our kids curiosity without providing canned solutions for them all the time, as the OP says.
Again, different people are curious about different things. Some are curious about the workings of things around them, some about their origins/history, some about people, some about societies, some about how people think, some about plants and animals and life, some about the planet and the stars ... and some about stuff that they think has-nothing-to-do-whateosver-with-anything-but-in-the-end-hell-it-does (hint - math).
Perhaps we're in an era where polymaths are rare, but curiosity, though heavily fragmented, does live on.
