It seems many take the negative perspective of this finding - anecdotes about moments where management "doesn't get it" and tying that back to their lack of technical expertise.
What's missing from the discussion is the underlying foundation of the finding: in an average case, if your manager has technical expertise in your field, you're likely to learn a lot from them - that learning (and growth) is a major driver of job satisfaction. It creates closer relationships through shared understanding/experiences as well.
I'd also argue that simply being able to do the job and not developing the team in technical expertise yields similar job satisfaction as not having deep technical expertise at all.
