This article is taking some liberties with the word "prodigy" that I disagree with.

If the way you nurture a talented student is via "intense drilling", I would argue that the student is not a prodigy in the traditional sense, but a talented and determined student who may or may not be dealing with parental pressure.

The actual prodigies I've known absorb information and gain skills without significant effort - I knew someone who enrolled in a calculus class, skimmed through the book in a week or so, and then would only show up to class for tests (which they would ace).

So the article conclusion doesn't surprise me - inflict relentless training on a young talented person and yeah maybe they won't want to do that as an adult.

But as far as actual "prodigies"? There is no burn-out because there is no (or minimal) effort. The choice of whether to stick with an area of interest through adulthood is more of a personal preference than anything ingrained.
