In my experience when a job description is posted requiring a "full stack developer", they mean someone who can do some UI, business logic, and DB coding. It doesn't mean they're looking for someone who is an expert in every aspect, or has skill sets in all 18 tiers that are listed in the article. So yes the definition of "full stack developer" that this article uses means that there are exceedingly few full stack developers. But the definition implied by most job postings I see are a lot more reasonable than this article.
