To be fair though, that's true for every profession or skill.

I've seen something similar where people were surprised that you can use an object storage (so effectively "make HTTP requests") from every server.

Conversely, we had millions of server huggers before, who each knew their company's stuff in a way that wasn't really applicable if they went somewhere else.

Every company used to have a bespoke collection of build, deployment, monitoring, scaling, etc concerns. Everyone had their own practices, their own wikis to try to make sense of what they had.

I think we critically under-appreciate that k8s is a social technology that is broadly applicable. Not just for hosting containers, but as a cloud-native form of thinking, where it becomes much easier to ask: what do we have here, and is it running well, and to have systems that are helping you keep that all on track (autonomic behavior/control loops).

I see such rebellion & disdain for where we are now, but so few people who seem able to recognize and grapple with what absolute muck we so recently have crawled out of.
