Malcolm specifically said that "it takes 10000 hours of deliberate practice to achieve mastery."

There are two component here: 1) 10000 hours and 2) deliberate practice.

What op present us are "you can ditch 10000 hours because deliberate practice is enough" but when you go through the article it shows that all test subject were trained for very narrow set of mastery for short time period (bean bag tossing, microsurgey) or very wide set of mastery for long period of time (football play)

moreover, Gladwell's use of practice in the book I think is more meant in the general sense (as in practicing an art) because those 10000 hours are not necessarily "sitting down and playing czerny on the piano" but also things like "playing around on a mainframe" - basically anything that gains you experience, which is usually going to be more variegated in the way that the article suggests.
