Earlier quoted context omitted.
The liability for killing someone can include prison time.
Good. If you write software that people rely on with their lives, and it fails, you should be held liable for that criminally.
The line should be where a person tells others that they can rely on the software with their lives - as in the integrator for the end product. Even if I was working on the software for self driving, the same thing would apply - if I wrote some alpha level stuff for the internal demonstration and some manager decided "good enough, ship it", they should be liable for that decision. (Because I wouldn't be able to stop them / may have already left by then)
