It's to early to conclude it's only a software bug. And blaming programmers is the absolutely not the way to avoid issues. Humans makes errors, always. Programmers or not. Some errors are unfortunately dramatic (talk about this to surgeons for example). Now to remove the human factor as much as possible, there is processes and engineering techniques. If the failure was indeed caused by the software, and not by other defects in the plane design, the real question is how could it pass any safety check. For me, in any scenario, the first really wrong thing is how the plane passed all safety checks without the defect being detected, internally at Boeing as well as externally. As more information unveil, it seems that the prime suspect is the pressure to release a plane too quickly.
