Imho the fundamental problem here is software & system complexity has grown to a scale where people (read: developers, system admins & the like) can't fully understand the tools they deploy. Or the implications of a failure somewhere.

That's okay if components are small, have well-defined boundaries / dependencies, are easy to inspect, and all that is rigidly enforced.

Obviously that's not where we are.

On the bright side: in most cases that complexity is self-inflicted, unnecessary, and can be side-stepped if so desired. Problems we're seeing don't occur by necessity: they occur because we've complicated many jobs more than those jobs need to be complicated.

Go back to first principles, cut bs wrappers around everything, and move on.
