3) Marketing, PR, and BD make a lot more sense in industries where tech isn't the dominant factor.
I won't disagree, but I'd be wary of overstating the importance of that point. Marketing definitely matters for technology (esp. when you take a broad, holistic view of what 'marketing' is). There are more than a few stories in the annals of the tech industry where a nominally superior tech lost out to an inferior product that had better marketing around it.
On that note, the book In Search of Stupidity[1] catalogs a pile of tech marketing disasters from over the years. I'd recommend it to anyone who thinks "marketing isn't that important" or anything along those lines.
