MBA is highly dogmatic and highly prescriptive. It does not delve into the why. I can't draw a better analogy than the worthless certification courses that you'll find on the CVs of second-rate engineers.

If you want someone who is leading their field in some technology, you look for researchers, people with significant on the ground experience, people who understand the first principles, limitations, and capabilities of that technology. If you just want to fill the job slot with some rando, you'll settle for someone who has some stupid certification in said technology and thinks there's only one right way to use it because that's all they've been taught. MBA is the same thing but with a lot more self-congratulatory jerkoff. If you're in the right industry, it becomes easy to spot recent MBA grads. The way they talk to their subordinates, the way they talk to their superiors, even the way they act during downtime around coworkers - it's all part of the cookie cutter recipe they were fed and blindly follow. It's nauseating.
