Antiquated pilot skills
Airline pilots do not need to learn pilotage, dead reckoning, VFR rules, stalls, steam gauge attitude instrument skills, most of WX charts ect.... Most of that stuff is as worthless to a new pilot as an E6B.
Where in the near future will new pilots even be able to develop such skills? New planes are all glass with moving maps and GPS.
At one time it was considered essential for pilots to memorise Morse code, learn tail wheel skills and pilotage.
In the near future airlines will have their own sponsored initial training sources and pilots will fund the cost of their own training. UAL and the rest did something similar in the late 1960's. No pilot shortage.
Oh yea, and hand flying IFR will be considered to be an emergency procedure only practiced in the sim.
