The only two real issues I've got with this article are that it limits itself in scope to the "gifted" and that it limits itself to children.
As for the latter issue, I suspect that this may fit into a broader work or area that the author presumes readers are familiar with--these issues are certainly seen in teenagers and afterwards.
As for the first point, a bit of a cliche but still accurate is the saying "The rain falls on the just and the unjust alike"; at some level, everyone I've met sharp or dull, gifted or not has run up against some version of the four issues (death, freedom, isolation, and meaninglessness). It may take until middle age and a house and a picket fence and seventy grand in debt, but it hits eventually.
One of the best realizations I've come to is that everyone, at some level or another, faces these problems in their own way and that I should try and respect their experience--because for them, their existential conflict is at least as severe as my own, their circumstances and stakes at least as dire.
What struck me as interesting was the author's specifically calling out touch as a mechanism for grounding and comfort--this struck a chord with me when I read it. It's part of the reason I have dogs: there is a very real touchable physical presence of pet, something to hold and hug and pet when you're mulling over some of the day's shittiness.
tl,dr; life's a bitch, get a dog.
