The point being that automation covers many deficiencies in technique to the point where a less experienced pilot can be unaware of, or forgets to check trim settings and fails to use secondary instruments to infer missing information when the primary systems fail.
We can automate most .. improve existing systems .. invent others .. make extensive training pilots ... all this is possible .. this is often done ... everything evolves
But one thing is certain .. the man is always the same .. with its strengths and weaknesses .. and that no automation or system will not be able to change this
There will always be people who have a particular momment do the opposite of what is required and action will succeed even with all the barriers placed to prevent them of such actions
