I must have misunderstood what "Servant Leadership" actually is. I identify as such, but I also do just about all of the "Transparent Leadership" things called out in the article. I may have to re-evaluate my orientation.
There's only one place I disagree and that's when it comes to empowering the team to do every last thing within your charge ("become redundant"). Depending on the organization, there are some actions that only a manager is empowered to do. Someone still needs to be present to weigh in on disputes/arguments, break ties, handle performance, reviews, interviews, PIPs, dismissals, and handle _other_ managers when necessary. It's simply not possible delegate these things and in the case of dealing with other managers, can imperil a person's employment.
Also, I would caution anyone to avoid directly comparing management to parenthood, even as a metaphor. A lot of people have terrible parents, and so model the worst behaviors: they can't nurture a houseplant let alone a human being. I've seen people like this bring the worst possible models for management into the workplace this way, and they do a ton of damage to businesses, psyches, and careers in return. Instead, I urge anyone to look to the carpenter/gardener dichotomy and how good leadership requires a bit of both:

You did not. Or, at least we share an understanding of what the term means which differs substantially from the author's.
