'CEO Cloning': Is Anyone Else Going to This Extreme? I will not promote

CEO cloning is where the CEO takes an employee they believe is a long-term rockstar, and essentially duct tapes them to their hip so the employee can learn to mimic how the CEO thinks. And then that employee 'clones' other employees. On My First Million Podcast, Mr. Beast discussed his concept of 'CEO cloning,' which he attributes to a lot of his success. Yes, in some ways, this is fairly normal and obvious. But I mean explicitly and very intentionally doing this regularly, like to the extent where the employee lives with the CEO for a bit. Or at least close to that level. I'm curious if anyone else here has done this, know CEOs who have, or have any thoughts on it? Link to the clip in comments.
