Thank you for sharing your amazing experience. But don't you think if you weren't told about a critical system that has the potential to bring down an aircraft, you would feel the need to be trained properly on it? I am in the cybersecurity space and it has been a proven fact that CBTs (Computer Based Training) is not as useful as to exposing an user to a real threat in a simulated environment and providing the appropriate education/guidance at the point of failure. Similarly, in this case, if MCAS could bring a plane down and completely hiding it from folks who fly it won't really help them - instead, it would hurt them, which, unfortunately, in this case, hurt 350+ souls. Having a self-guided training is good, but let the pilots get a feel of the actual system in action on a Sim.
