When you hold yourself to the same legal and social standards as actual accredited engineers, of the type who build things like airplanes, you’ll be in a better position. Right now the software works wants the benefits of the unregulated Wild West, without the consequences. Such a scenario simply cannot last, and in the absence of self regulation and setting of standards, the legal system will step in. It’s slow, it’s clumsy, and it’s inevitable.

But engineers (real engineers, not self-styled unregulated ones) are already liable for their negligence and failures.

Precedent:

229 If a builder builds a house for someone, and does not construct it properly, and the house which he built falls and kills its owner, then that builder shall be put to death.

230. If it kills the son of the owner, the son of that builder shall be put to death.
