Automation saves lives. A system can be programmed to handle 99% of eventualities but it is always that 1% that catches designers out. It is a human condition that we only focus on the mistakes. In fact it is human beings who make the most mistakes. No matter how well you train them, individuals will often respond differently under real stress (i.e. not in between coffee breaks in a simulator) and not perform as expected. Computers will always respond the same way. Of course, like people, computers need valid data to make a correct decision so keeping sensors clear of obstruction is important. That goes for humans too, and the inner ear for instance can misinterpret which way is up when other sensory data is missing. But even if data inputs are correct, if an external force is applied which pushes the aircraft outside its flight envelope then that is the fault of whoever exposed the aircraft to the risk. That could be the pilot, weather men, ATC, loaders or equipment - and its usually a combination of more than one of these - so don't blame the automation.
