Are we naive in trusting brainless COMPLEX machines like modern jet planes "

Can there be a more harrowing experience ( apart from a condemned prisoner waiting for a pardon on death row on day of his scheduled execution ) than being a passenger in a high in the sky jet plane suddenly in TWILIGHT ZONE " frozen " doom time ? Are we naive about trusting BRAINLESS , very complex , machines ? Or even BRAINY AI machines ? Perhaps in the far distant future we will have " Guardian Angel " robots ? We still have an unconscious wish that our innocent children have divine " guardian angel " protection. But on a passenger jet five miles up in the atmosphere don't count on the indifferent LAW OF GRAVITY being suspended ! And yet " indifferent " gravity holds our oxygen supply to the Good Earth . Try breathing without a spacesuit on the Moon !
