It's not the difficulty that is the problem, but a fear that it can't reliably deal with changing environment/edge cases/anomalies. It's a lot safer and comfortable to have "man-machine symbiosis" for many tasks where machines are used as tools by humans. Machines do most of the work but supervised by humans where humans do high level abstract decisions but most of the work is still done by the machine. Best example I can come up now is probably flying planes, they are mostly flied by the computer but I bet you feel safer when pilots are there even though they do almost no work.
