I think this model offers a useful template for team design.

The senior employee acts as the hub, with junior employees and AI agents working as the spokes around them. Instead of simply delegating tasks, that senior person shapes how the work gets done: teaching the AI systems and juniors what good looks like, and helping junior employees build judgment by working inside the same system. The junior employee learns from the AI by seeing how it approaches research, drafting, analysis and problem-solving; the AI improves because the junior is constantly correcting, refining, rejecting and escalating its outputs.

That’s where the training model changes. Historically, juniors learned through repetition, writing the first draft, building the spreadsheet, checking the details, sending the recap and slowly absorbing the standards of the job. AI will take over parts of that repetitive work, but it won’t remove the need for training. It changes where the learning happens: juniors are no longer just learning by doing the task from scratch, they’re learning by directing the task, judging the output and feeding better decisions back into the system.
