You can both be right. Like LLMs, McKinsey offers a combination of competence and bullshit. It hires bright, young, and freshly educated people who can go at problems with energy and a toolbox of the latest tools. Yet, putting a young person in a role like that is an hierarchy-disrupting tactic which can be seen best in the Church of Scientology where they find the youngest staff member they can find to be an "ethics officer".

A primary social hierarchy (Scientology, a corporation, Mao-era China) might feel threatened by various secondary and informal hierarchies (people who practice "the tech" on their own and make changes, workers who have the knowledge of how to do the company's task in their heads but not written down, sysadmins who keep a file of anyone who could possibly help them solve problems in their organization or with their vendors, fox cults, ...)

An accusation that is frequently leveled at McKinsey is that management brings them on to "launder" things they want to do, what I can say is that your slide decks are not just seen by the systems thinkers who are running the show but they are also seen by the people that the people who are running the show want to persuade.
