The F-35 may enter service with enough sensors and computing power on board to make the starship Enterprise look like sopwith camel but one computer cannot be upgraded and that sits between the pilots ears. You can have all the automation you want but for example during close air support having a single crew member fly the aircraft, watch the air to air situation and try to listen to a frantic soldier in a fire fight on the ground screaming for help to save his men is a big ask. I once asked an RAAF Super Hornet pilot about "helmet fires" and he told me that they sometimes get information overload on a mission with data coming in from the radar, targeting pod and link 16. When his WSO spoke up he said: "That only happens to nose gunners".
The point they made was two heads are better than one no matter how much wizardry is on board.
Other wise I will defer to Courtney's professional experience ( at least until I can fly FAC missions in a C182).
