Containers: love 'em or hate 'em -- whether you think they're the hottest new thing or yesteryear's same ideas in new clothing -- the both rapid and sustained rate of adoption of recent container technologies says one thing clearly: We Were Missing Something. But what, exactly? And have we found "it"? Or are we just beginning to uncover something new about the way we all, in our deepest hearts, wish computers would be? In this talk, we'll survey where containers came from, and question where they’re going: a discussion that crosses package management, releasing, deployment, immutability, reproducibility, and questions how meanings of all these things are now changing.
