The wrong in this, is the extent they went to with this. I mean, name your servers whatever you want, but hiring an artist to draw the servers personalities and then writing a blog post about this? Like common, that's something a child would do about their favorite toy. At some point, people need to grow up.
And I guess the other "wrong with it" is the fact that it just wastes human potential. Build robust software and take pride in this, not it naming your servers bob and lola.
I disagree with your definition of what 'growing up' is about. There is something lost in the world where making silly but fun things is frowned upon. And yes, fun is subjective.
I don't share my kids excitement about most things, but I'm genuinely happy they enjoy themselves so much. Being able to use the same notion to all people, not just (your) kids is part of growing up in my books.
The only way to properly realize human potential is to have no fun when doing your work? Are you really sure you want to live in a world like that?
Sure, not using a naming scheme and not hiring the artist would have unlocked the potential to make their software soooo much more robust…
I reject your joyless reality and substitute my own.
