If I may say so, I believe in training, training, training, and hands-on practice in real situations.
I'll just relate quickly that a railway tried to run its locomotives without people in the cab, which is a bit like having a simulator simulating a flight. It didn't work out because there was too much in the way of wind, animals crossing the track, and unexpected rain bursts; and the situation wasn't dealt with adequately by the machine.
Again, a machine cannot perhaps easily invent a fox or a deer that dashes across the runway, or a flock of geese that flies into a motor. It can be done, but I have not heard of it being done a lot.
In the end, in a situation where climate change is making things more unpredictable and unstable, the real world and training in it seem to me to be what will help prevent accidents on landing and takeoff.
