But anybody who has been paying attention has known that any job is "just a stint" since at least the 90's, if not the 80's. A big part of the Re-engineering[1] push of the 90's involved reducing costs, at least in part by reducing head-count. And before that, you had the 80's LBO[2] craze, which resulted in dramatic layoffs at many companies.
As a Gen-X'er who grew up in the 80's, I have never expected to have a life-long career at a single company, and I can't imagine many - if any - of my peers imagining that either. In this regard, there's nothing unique at Netflix. All jobs are essentially "temp" jobs in this day and age.
