When Google acquired Motorola, snotty Googlers paraded around claiming to be at least 2X smarter than the average Motorola employee. They publicly proclaimed to turn around a sinking ship and produce iPhone killers, emphasis on plural, within a few quarters.
But none of that famed productivity or genius amounted to measurable results.
An objective analysis will reveal that Google's main business - online advertising- has been so damn profitable for them that they've absorbed hundreds, if not thousands of failed projects burning billions. One might argue that any other company with the ability to subsidize this this kind of failure will churn out scores of projects with little chance of success, projecting an image of productivity.
Ponder on this for a moment, if everyone outside core advertising, AI, YouTube and Android are fired from Google tomorrow, their revenue and profit will barely budge. What % of Google do to think work on those products? So how productive do you deem the average Googler is?
