The title is clickbait-y (the harbingers are never identified) and the Ars author&#x27;s conclusions have little to do with the conclusions of the researchers.<p>Example: &quot;If something appeals to them, it’s unlikely that it will appeal to the mainstream.&quot;   No, it doesn&#x27;t say that about the general cases -- that&#x27;s like saying &quot;if a (harbinger) likes Star Wars, it&#x27;s unlikely that Star Wars will appeal to the mainstream.&quot;    The only universe of products that is relevant to harbinger behavior is <i>failed</i> products.
