Of course that would be ridiculous. You're trivializing the author's point. I'm not sure you've actually read the article in full. The author admits the difficulty in measuring it and that we may have to rely on "non-scientific" measurements.
Many of the tech robber barons and VCs (who call themselves "angels") carry the air of "my winnings are entirely of my own making". They rarely acknowledge the role of good fortune (in various aspects) in any meaningful way.
They inhale their success too deeply, as Michael Sandel memorably puts it.
