Again, not sure you read the article closely.

I think I made it clear that it's a case of "Yes, and..." not "either/or"

The bias is not the only source of the problem. As you point out correctly, the marketing staff falls short, too.

The real problem I define is the never-ending feedback loop between Silicon Valley's bias against marketing and the relatively low quality of marketers in the talent pool that results.

Hard to say whether the chicken or the egg came first, but it doesn't really matter.

As for the framework vs the "laundry list of stuff" I don't like...

This is just the opening salvo. IMHO, great marketing and great products often (not always) arise from a deep understanding of and insight into big unsolved problems, unmet needs, and unfulfilled desires.

This post is my articulation of a very big unsolved problem and all of its consequences.

More on the solution soon.
