As someone who works in big tech with a partner at a similar big tech company _but with player coaches, DRIs, etc_ it is basically the same thing except messier.

Your manager who used to just focus on motivating and unblocking their people? Now they have to ship code too since they’re a player coaches! You’re a DRI who needs management to get your project unblocked? Too bad your player coach who has to ship code now also has 20 direct reports because the hierarchy was flattened so you can’t get time with them until next week and are blocked until at least then.

It is the hot new trend from the “thought leaders” who have all consistently copied each other’s bad ideas for the past 10 years.
