This sounds like surface level wisdom if you are in your earlier career. I see several problems with this advice, but here is the most obvious one: this only works if you want to become a manager.

It used to be the case that the only way for engineers to advance their career. But we've long moved since and now you can have a long career and get very high in a company without management responsibilities. The examples given in the blog post are exactly what I would expect ICs to do, not managers.

Do you want advice to get promoted? if your company has a formal career ladder, look into the process and optimize for it. Despite people grievances, this is still the fastest and easiest method to get a promotion (shocker!).
