How do you know senior programmer won't ask AI and won't complete this task in 20% of time it would take the that junior because he already knows how to set up all his tools, workspace and fix small bugs without having to ask AI about each thing separately?
Also this is more of physics than programming problem. You don't hire seniors to write pendulum simulations, you hire them so they can make sense of huge complex legacy undocumented system written in archaic framework with vague business goals and unholy spaghetti code.
