>Languages don't create bug

No but they allow certain classes of bugs to be written.

>people create bugs and there will always be bugs.

To true, but I take that to a completely different place. Some languages require super human amounts effort to avoid bugs that are easily machine checkable, or the language could offer tools that don't even make such situations possible. Picking a safer language allows you to spend some of your bug avoidance effort in a more profitable way.
