Well, he did cherry-pick one joking comment out of a well-intentioned post in order to say I have a bad attitude, so that's not exactly welcoming. And very patronizing, considering I have actually done that kind of work with Salt Stack a few years ago, and just don't want to bother with it at the moment because I have other priorities.

I learn new things every day, and one day, Docker was that thing. I am now better at release engineering, cool! But I also lost a day of working on shipping value to users and actually having fun, which is less cool. That's why PaaS has been helpful to certain kinds of people; it makes the curve of progressive disclosure necessary to deploy stuff a little flatter. My hope is that we can make more kinds of things really easy to do the right way, and not yell at people who just want to have some fun.
