I think the author vastly over-estimates what it takes to be a proficient technologist. He can figure things out. That's all you need to have a job/career in tech. Because technology is hard enough that the vast majority of people just won't want to do it. Everything else is just stuff that makes that job/career easier and more fulfilling.

2 Weeks is what it usually takes to catch-up with all new libraries in all the languages you care about. Not more. Easy as googling it and checking github explore, then trying each one out. Simple as that. Do that every 6months and you're set. What could go wrong? :)
