>My work is facilitating a particular type of technical safety audit (HAZOP) in the process engineering industry.

You had me here. I was about to jump in pointing out that things like auditing is probably one of the easier tasks for AI. Glad I read the rest before commenting though because I think you're spot on with what you said. Lots of things could be replaced by AI, but until AI becomes more advanced and lower cost to train, many of those applications just won't be feasible from a financial point of view.
