10,000 hours checks out. At 8 hours a day, 5 days a week, that's 4.8 years to master say a technology, language, or software stack.

Very convenient that it’s a nice round number.

Erickssons original number was more like 10 years of daily deliberate practice increasing drom 0.5 to a max of 4/hours per day iirc for experienced people. It was roughly observational based on violinists and pianists. The original paper was interesting.

Yeah I think it was Gladwell (shocker) who shoehorned himself into the concept and made up the 10,000 hour rule.

Indeed. “10000 hours” rings as true as your average Ted Talk.
