Does anyone see all the data cited in the article as only kinda tangentially related to what seems to be the main idea of the post? Isn't it possible that "corporate america" is being disrupted AND their are less new companies being formed? It seems simple enough to prove, if only 5 new companies started this year and all 5 grew to be as large as Google, that would be some serious disruption. I am not arguing that their thesis is wrong, it just seems their supporting data falls short of proving the case. I think a more telling dataset would be a similar type of time analysis but looking at the top 500 companies by market cap. How many are new? And that might not even really be getting at the author's real point. Because, he's talking about upsetting existing industries. For instance, sure Apple, Google and MS are pretty new. But did they disrupt an industry or just make it through as the winners of a newly minted "tech" industry? I'm actually asking because this question and thesis is genuinely interesting to me.
