I don't see the point of just not addressing the article. It quite specifically argues that as technology isn't emerging any more so startups can't commercialize those emerging technologies.

Many of these companies were absolutely obvious, just hard to get right. "Everyone" were creating social networks at one point when Myspace was big and Facebook hadn't yet won. And music streaming after Napster, or "mobile blogging" as an Instagram predecessor, or video streaming with Flash, or ... .

Of course it was hard to get it right, but that is why you had a shot to make something with "a good brain and a keyboard". Many companies who didn't make it all the way still sold on some merit of technology. Many VC firms aren't looking for that any more, but things like marketing and sales.
