The weird thing is that people tend to trust computers more than mechanical systems, when it should be the other way around. Yes, in theory, computers can do a better job, but as long as they have to depend on flawed software designed and written by human beings, they may actually be more dangerous than the mechanical systems they replace.
Ever experienced a frozen Handle due to a struck elevator cable? Might make you feel different about mechanical systems being less flawed.
