Error bracket within any decent computer program today is much tighter than the same for us, humans. Full automation of flight ops is, therefore, inevitable. Better get used to it and let it go as soon as possible. Professions disappear all the time. This is part of our human evolution. Being pissed off about airline pilot vanishing it is like being pissed off about commercial sailing ships - for many centuries an economic backbone for most countries - having eventually become redundant.
Yes! One Sully doesn't make summer. Poor piloting is the worst advertisement for human presence in the cockpit As more and more human factors are discovered it's a message that for a human to work safely and efficiently 100 things have to be changed or done differently. Technology may find it safer and importantly cheaper because it's a business after all to replace the human. It is sad but as you say it's part of evolution. It may start with single pilot, then cargo flights and then pilotless. Will accidents happen? Surely there will be some but as long as they are significantly less it won't matter. People will board if it costs less. Some may even see it as an adventure and the phobics are uncomfortable even now.
