> Like 99% of news reported computere glitch's it is some human mess up that caused it
If the system allowed the user to do something that impacted safetey in such a way, then the computer glitch is that the computer should stop that sort of thing happening. Human error happens a lot and you have to account for it in your designs.
Of course there are times when you have to trust the user because it is not practical to do those tests (in which case the human should have procedure to follow that mitigates the risk), and instances where the user wil override the checks (when the machines say "I really don't think you should do X because Y, click 'I understand the consequences of my propsosed action' to proceeed") - then it is genuinly human error is something goes wrong.
