This is not the kind of comment HN needs more of. A better version would (a) drop the snarky putdown, and (b) actually say what Google's conclusions are. Then readers could decide for themselves to what degree those findings contradict these, instead of being told what to think.
and apparently very few on HN in general, seeing how this piece was upvoted.
Google has been studying their process in the last few years and are reaching different conclusions than these guys.
Leave it to the reader to ascertain which group has more validity.
