it sounds like a lot of the negativity revolves around devops. that's understandable. it's part of a pendulum that swings back and forth. devops and docker as topics aren't really mutually inclusive.

docker, however, is more about the abstraction of complexity stemming from the industry's overall drive toward scalable, distributed applications and development teams. it's more analogous a developer saying, "why do we even use virtual machines?!? bare metal is way faster!"
