I’m also retired from a technical field, and I did bother to learn how to analogize and narrativize and graphically display many of the complex and technical things I often needed to convey to people that didn’t have my skillset.

Nothing I said is false.

I didn’t say marketing wasn’t important to a business.

I just said I find it fundamentally disdainful, the same way I would find a chemist who specifically only develops neurotoxins disdainful.

Yet, sometimes, in some contexts, necessary.

Finance? I didn’t knock finance. Finance is very often highly intensive with complex math and series of complex rulesets.

I often find finance disdainful, because often, finance just uses their extremely complex skillset to functionally lie via statistics.

Anyway, yeah finance is needed.

‘Leadership’?

Do you mean, ‘owners’?

Or do you mean people with actual team leading and decision making skills, who have a solid and broad sense of responsibility to employees and consumers, and ability to own their own mistakes?

Because in my experience, ‘leadership’ in most complex and large organizations display the exact opposite qualities as those.
