I also admit that I still have no idea what a Kubernet is or what Docker and containers orchestration or any of those things are all about. I mean, I visited their web sites and read a few wikipedia articles. But I'm primarily an embedded/mobile guy and whatever problem space containers solve is something I've just never even remotely encountered.

Same with enterprise software development. It's kind of neat that the world of software engineering is so big that one can go 20 years into their career and be totally experience-deficient in large spaces of the industry.
