Perhaps there is no such thing like absolute truth.

In category theory / ologs, a formal method for knowledge representation, the result is always mathematically sound, yet ologs are prefixed with "According to the author's world view ..."

On the other way truth, even if it's not absolute, it's very expensive.

Lately AWS advocates a middle ground, the lightweight formal methods, which are much cheaper than formal methods yet deliver good enough correctness for their business case.

In the same way MIT CSAIL's Daniel Jackson advocates a semi-formal approach to design likely-correct apps (Concept design)

It seems there is a push for better correctness in software, without the aim of perfectionism.
