Why spend $$ on a high performance air-superiority fighter when you can have one flying truck (F-35) controlling 20 cheap air to air drones? Even if a drone is just a disposable way to draw fire it's still a deal compared to a manned F-22.
The problem is that for air-superiority the F22 has incredible performance. One of their biggest problem when they launched was that pilots kept blacking out from the g-forces and suffering lasting effects. A drone to match it isn't going to be that much cheaper because the life support isn't really the most expensive part of the package.
Making drones like that is only worth it if an adversary has something worth destroying that can't be done with cheaper hardware like cruise missiles.
