Kubernetes isn't a solution. It just pushes the problem down the line. Fundamental problem is most software developed these days aren't packaged properly. The devs just ship the code to production. The hacks that they used to get the development going stays in production.
For example, you don't need a docker container to deploy Mysql, although you can deploy Mysql inside one. But most development processors are so badly managed that one product has many conflicting libraries and dependencies. Eventual requiring each component to be isolated within its own container. Finally leading to an unmanageable number of containers requiring Kubernetes to manage the mess.
newer tech allows lower skilled developers to build programs. Which in turn leads to more tech to dumb things down even more. Resulting in more inefficient programs overtime.
I did it once. Did absolutely nothing of value for 8 months and went back to work. I had savings so I was ok financially. Mostly played games and watched movies. Traveled a bit. Didn't realize I needed it until I was doing it.
