Or, "Why can't Google retain talent?"

Or, "Average Googler works 4 years; stockholders see consistent gains."

I struggle to find the author's point. By the title alone, this tenure seems to be some vice of Google and tech in general. Furthermore, it's an indictment of an entire class of workers.

Is Exxon really that much better a company than Google? It must be, because the employees stick around for 2 more years!

Google, as a company, still changes entirely over a four year period. That average tenure sees through a whole generation. I could write an article claiming it to be the defining characteristic of a successful company.

This is as good as gossip.
