“[Computing] is pop culture. I'm not against pop culture. But pop culture holds a disdain for history.

Pop culture is all about identity and feeling like you're participating. It has nothing to do with cooperation, the past or the future — it's living in the present.

I think the same is true of most people who write code for money.

They have no idea where [their culture came from].”— Alan Kay

organization; and then how you play into those.

Until you take the time to sit and understand that, DevOps for the sake of DevOps doesn’t matter.
