Top post: @giffmana “Ahh you are at risk of becoming a Bezos-style manager! You need to tell them about each other to avoid this kind of behavior. Put yourself into their show: they though they have the whole cluster and discover someone else working on something similar using some of the gpus!! You are on the verge of discovering BigCo politics from first principles 😁”
