So you're saying companies should move to k8s and then immediately move to bash scripts

No. I am saying that companies should have their engineers understand why k8s works and make those reasons an engineering practice.

As it is today the pattern is spend a ton of money moving to k8s (mostly costly managed solutions) in the process fix all the bad engineering patterns, forced by k8s. To then have an engineer save the company money by moving back to a more home grown solution, a solution that fits the companies needs and saves money, something that would only be possible once the engineering practices were fixed.
